³ ³

³ - COBRA FOR VIPER GC V1.1 - ³

³ ³

³ 14th of april, 2005 ³

³ ³

³ ³

³ WHAT'S NEW ? ³

³ ³

³ - Built-in Audio Fix, that could be Enabled/Disabled in the Config ³

³ Menu for full backward compatibility with your old backups. ³

³ - Music Player in Disc Explorer! Select an audio file to play it. For ³

³ now only ADPCM audio streams are supported (*.ADP, *.PCM, *stream*, ³

³ etc.), the GC streaming format. Support for more formats, including ³

³ MP3, is coming in a next release. ³

³ - Optimal DRE Handling, read more below. ³

³ - Improved Direct Boot mode Compatibility, now it should be compatible ³

³ with every good media, including DVD+R. ³

³ - No need to enter Disc Explorer anymore to boot MultiBoot discs, just ³

³ select Direct Boot Disc and the Cobra BIOS will detect automatically ³

³ if you inserted a GC Original, DVD-R, DVD+R or MultiBoot Disc ! ³

³ - Fixed a MultiBoot compatibility problem. Now it should work properly ³

³ with every images. ³

³ - Upgrade with the Disc Explorer from Cobra 1.0 if you want to keep ³

³ your AR codes and configuration intact. ³

³ - And some more bugfixes/changes ³

³ ³

³ About Disc Read Error handling, we can't help you if you use a bad ³

³ burner, media or if your laser is not tweaked correctly. But we've ³

³ improved the error handling code A LOT. Here is a small experiment ³

³ we don't recommend trying at home, except if you know what youre doing: ³

³ You can remove the spinning disc for one second while it's playing a ³

³ movie or loading data. This will trigger some serious read error with ³

³ any other BIOS :-) Now put the disc back in quickly and it will ³

³ continue loading, without a crash! ³

³ ³

³ ³

³ FEATURES ³

³ ³

³ - Direct boot of all media, without swapping! ³

³ - Automatic Media Detection: Insert disc, turn on GC and play! ³

³ - Supports all regions PAL / USA / JAP ³

³ - Play originals or backups from any region, thanks to the built-in ³

³ region-free feature ³

³ - Built-in Audio Fix, that could be Enabled/Disabled in the Config ³

³ Menu for full backward compatibility with your old backups. ³

³ - Idle-bug free (no more Disc Read Errors when the drive is resting :-) ³

³ - Unique MultiBoot feature: put several games on one single disc! ³

³ - Disc Explorer to browse the content of original GC discs or DVDs and ³

³ that allows you: ³

³ - To flash your Viper GC by burning the flash file on a DVD ³

³ - To execute homebrew programs (.DOL) from DVD, and enjoy many ³

³ already-released homebrew productions! ³

³ - To play music, for now only ADPCM files aligned on a 32kb ³

³ boundary are accepted. This is the format of all GC games that ³

³ are using audio streaming, so listen to those games songs! ³

³ - To run the game you want from a MultiBoot compilation ³

³ - To load cheat codes from disc into Viper GC Memory ³

³ - Powerful Cheat Code System compatible with Action Replay codes, ³

³ codes are stored in the Viper GC Flash so no memory card is needed! ³

³ - Cheat codes can be either entered using Cobra Menus or loaded from ³

³ a file using the Disc Explorer ³

³ - BIOS Configuration stored into the Viper GC Flash ³

³ - Selectable default boot action (Main menu, Boot disc, Original BIOS, ³

³ Disc Explorer) and special boot action (when the X key is held) ³

³ - Calls Original BIOS Game Loader for 100% compatibility ³

³ - Supports all hardware revisions (including DOL-101 units) ³

³ - User-Friendly GUI ³

³ ³

³ A Swap disc option was left in (called "Change Disc" as you could also ³

³ replace a backup with another backup) to be totally backward ³

³ compatible. Read more below ³

³ ³

³ So what do you need exactly ? ³

³ - A Viper GC chip ³

³ - This very flash file ³

³ - Some Compatible Media and a DVD-burner ³

³ ³

³ ³

³ USER MANUAL ³

³ ³

³ - If you want to use full-size DVD-R you can remove the top of the ³

³ console. Team Xtender will be releasing replacement lids compatible ³

³ with full DVD-R within two week. Best of all, we learned this week ³

³ that they will be officially Viper GC branded! ³

³ ³

³ - Flash the Viper GC with this BIOS then remove the parallel port ³

³ connector from the programmer. If you prefear you can flash this ³

³ BIOS from DVD if you have Cobra 0.3+ already running on your chip. ³

³ We've heard Viper Team will release an USB programmer for the chip ³

³ soon if you prefear USB. ³

³ ³

³ - Turn on your GC with the disc you want to run. It can be an ³

³ original or a backup, but if it's a backup it should be filled with ³

³ 1.3GB of data at least (for now). If you have a black screen coming, ³

³ it's probably beause your Viper installation is not clean. ³

³ ³

³ - While turning on your GC: ³

³ - Hold Y to go to Main Menu (if it's not your Default Boot mode) ³

³ - Hold X for the other boot mode (can be set in Config Menu) ³

³ - Don't hold anything for Default Boot Action ³

³ ³

³ - Select "Direct Disc Boot" if you want to play a backup or homebrew ³

³ program from DVD. If you have problems using the Direct Disc Boot ³

³ method with your media, you can still use the Swap trick. ³

³ ³

³ - If you want to use the old Swap Trick Method (for discs that are ³

³ not full or that have problems to sync with the Direct Disc Boot) ³

³ boot your GC with an original disc. Then choose the "Change Disc" ³

³ option and follow the instructions. After the swap is done, you ³

³ can select Direct Disc Boot option again. ³

³ ³

³ - Select "Original BIOS" if you want to play an original Game ³

³ compatible with your GC region, or if you want to go into the ³

³ Original BIOS menus. ³

³ ³

³ - Select "Configuration Menu" if you want to change your Cobra BIOS ³

³ configuration. The options are quite self-explanatory. ³

³ ³

³ - Select "Disc Explorer" to enter to browse the content or your ³

³ original GC discs or DVDs. Supported file systems are FST ³

³ (GC File System) and ISO9660. Joliet encoding is not supported in ³

³ ISO mode. ³

³ ³

³ - Enter "Cheat codes" to select, enable, disable and edit cheat codes ³

³ ³

³ - Enter "Disc Explorer" and select a .VGC file if you want to reflash ³

³ your Viper GC without the need of the Parallel port programmer! ³

³ ³

³ - Enter "Disc Explorer" and select a .DOL file if you want to run ³

³ a homebrew program! (You can put up to 1.4 GB of homebrew things on ³

³ a disc. We hope this will give some inspiration to emu authors :-) ³

³ Our DOL loader is not perfect for now and works for around half of ³

³ the public homebrew programs. Here are some of the programs booting ³

³ successfully: ³

³ GC-Linux, Ascii Fighter, DVD Browser, CTR_GCS, CTR_SND, GBQ Gameboy ³

³ emulator, PSOLoader "It's working" demo, Maze, Nitrorally, Yeti 3D ³

³ 3D engine, Chip8 emulator, Snowlords game, Terranigma, XRick and ³

³ probably many we missed! ³

³ ³

³ - Enter "Disc Explorer" and select a .VGC file if you want to reflash ³

³ your Viper GC without the need of the Parallel port programmer! ³

³ ³

³ - Enter "Disc Explorer" and select a .COD file if you want to add ³

³ cheat codes for a game without the need to enter it using the pad! ³

³ ³

³ - Make sure that the "lid passthru" wires of the Viper GC are ³

³ installed correctly or the disc won't spin. ³

³ ³

³ ³

³ DIRECT BOOT LIMITATIONS ³

³ ³

³ THE MEDIA ³

³ ³

³ The GC drive in its default state only eats high-quality DVD-R and ³

³ a few MINI-DVD-R. But a couple of weeks ago, speedi from the afterdawn ³

³ forums found a nice way to tweak the laser so it reads almost any burned³

³ media including some DVD+Rs. We recommend doing this laser tweak if you ³

³ have any problems reading your DVDs. We are no laser experts, in fact ³

³ we think it would be more appropriate to just lower the value of the ³

³ variable resistor instead of setting it to an absoulte given value, ³

³ but lots of people including us have been using this laser tweek for a ³

³ couple of weeks without any problem reported so far. For more info on ³

³ laser tweaking please read this forum post: ³

³ http://forums.afterdawn.com/thread_view.cfm/138930 ³

³ ³

³ You don't need to encrypt the disc or use a special burner firmware ³

³ to write the disc. Just burn your ISO/GCM (rename it to .ISO) with ³

³ Nero (or any other tool). ³

³ ³

³ ³

³ CHEAT CODES ³

³ ³

³ If you want to use cheat codes, enter Cheat Codes menu,select a game, ³

³ check the codes you want to use, exit the cheat selector and enable ³

³ cheats. ³

³ ³

³ To add new codes follow on-screen instructions. The codes are ³

³ compatible with decrypted AR codes. You can decrypt AR codes using ³

³ the great GCNCrypt by Parayste. Never enter the first code of a given ³

³ cheat code (validator code). You can also put .COD files on a DVD and ³

³ load cheat codes from there, each file corresponds to one game. ³

³ ³

³ Cheat codes are working for backups and original games. ³

³ ³

³ For now we've reserved 4kb in Viper GC Flash memory to store cheat ³

³ codes, that should be enough to store a few hundred of codes. ³

³ ³

³ ³

³ TROOBLESHOOTING ³

³ ³

³ - If the disc stops spinning in the menu it means that the drive can't ³

³ sync with your media, or that there are not enough data on your disc. ³

³ In direct boot mode the GC is very selective about the media it ³

³ takes. If you have any problem please try the swap trick. If you ³

³ still have problems try with different media/burner. Make sure your ³

³ laser is correctly tweaked! We strongly recommend NEC burners, they ³

³ produce really good discs that won't give you any DRE. ³

³ ³

³ - Audio Streaming: Some games use a special audio streaming mode ³

³ that can be compared to CDDA. For now, the ISO of the file needs to ³

³ be patched with 0rbital's great ViperTemporaryAudioFix 1.1+. If the ³

³ ISO is not patched you'll have noise instead of music. We will try to ³

³ fix this issue so no patching is required. But in case we do, YOUR ³

³ PATCHED ISOS WILL BE FULLY COMPATIBLE and still work with music! ³

³ (so forget what is written in the fixer nfo file). Don't run the fix ³

³ on ISOs that don't need fixing as it will only destroy them :-) ³

³ ³

³ - Most multi-discs games are working, just play with Disc 1 until ³

³ you're asked to change disc and make a save here. Then boot with ³

³ Disc 2 instead. We started working on code to allow disc-change, ³

³ and we'll integrate it in a new release. ³

³ ³

³ All those problems could be fixed in a next update. ³

³ ³

³ Before burning an image, makes sure it is 1459978240 bytes long else ³

³ you may need to use the swap trick method. ³

³ ³

³ To know what's your GC Version code (2 digit number) go into Config ³

³ Menu, then Version Info, 2nd page. First digit corresponds to GC ³

³ mobo version, 2nd digit corresponds to drive version. ³

³ ³

³ IF YOU MAKE BACKUPS, DON'T USE ANY "WIPE" TOOLS TO SAVE SPACE. Unless ³

³ you know it's REALLY working. Most of thoses tools only work because ³

³ the current pso loaders patch libraries routines to emulate DVD. But ³

³ on REAL HARDWARE, each file/fst has to be aligned on a 4-byte boundary! ³

³ Else nothing will work. Audio Files (for audio streaming) even need ³

³ to be aligned on a 32kb-boundary ! So forget current "WIPE" tools until ³

³ they are fixed. But note that Garbage is NOT NEEDED by the GC. The ³

³ files must be correctly aligned that's it. So if your "WIPE" tool is ³

³ not changing the image size (meaning there's no relocation) then it's ³

³ probably fine. Use FSTFIX by LOONYCUBE to fix bad rips. ³

³ ³

³ ³

³ TECHNICAL INFO ³

³ ³

³ We'll release a command-line MultiBoot Disc maker next week if nobody ³

³ releases a better one before we do :-) Here are the specs for Multiboot ³

³ discs. Note that every image should be aligned on a 32kb boundary. ³

³ At offset 0x00: 43 4F 42 52-41 4D 42 31 ³

³ 0x40: Position of the 1st image in bytes (Big endian) ³

³ 0x44: Position of the 2nd image in bytes (Big endian) ³

³ ....: ...etc... ³

³ ....: 00 00 00 00 ³

³ ³

³ The MultiBoot feature is stealth for the GC so it's 100% compatible ³

³ with homebrew images. If you want to put several backups on one disc ³

³ you'll have to remove the garbage at first. ³

³ The maximum size of a MultiBoot disc is 1459978240 bytes. ³

³ ³

³ You can use Viper_Multi_Boot_ISO_Creator by LoonyCube to create ³

³ MultiBoot discs easily. ³

³ ³

³ ³

³ THE FUTURE ³

³ ³

³ Much more to come :-) ³

³ ³

³ ³

³ CLOSING WORDS ³

³ Melan for the /48 GC and to everybody that tried Cobra V1.0 and posted ³

³ constructive feedback. ³
