³ ³
³ - COBRA FOR VIPER GC V0.2 - ³
³ (Proof Of Concept Version) ³
³ ³
³ 15th of december, 2004 ³
³ ³
³ ³
³ You didn't expect it to be true, right? Well, guess what... it IS! ³
³ As of today, no need for PSO anymore, you can boot your code directly ³
³ from the GC drive using DVD-R or Mini-DVD-R! This also includes the ³
³ ability to boot your backups. 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 In fact, we wanted to release the first version of our Viper BIOS ³
³ around Xmas time, but it appears that some fucker leaked a -PRE-ALPHA- ³
³ version two days ago together with a screenshot (fuck you Vincenzo), ³
³ together with a screencap. We decided to release a proof-of-concept ³
³ version as soon as possible so that people can stop spreading rumor ³
³ about it (and DON'T USE the pre-alpha as it has some major bugs). ³
³ We feel it's totally natural that most people did doubt it was true, ³
³ as most of them have been waiting for such a solution for years! So ³
³ now those people can try the thing for REAL :-). ³
³ ³
³ USER MANUAL ³
³ ³
³ - Flash the Viper GC with this BIOS then remove the parallel port ³
³ connector from the programmer (well, their manual says so) ³
³ ³
³ - Turn on your GC with an ORIGINAL DISC in the drive. ³
³ If there's no Title Screen coming, but the original BIOS instead ³
³ it's probably that you messed up your viper install:-) ³
³ Check that it's clean (and no wires crossing each other etc...) ³
³ If you have a black screen coming, it's probably because you have ³
³ some wierd BIOS we don't support (and don't know about) yet. ³
³ ³
³ - While turning on your GC: ³
³ - Hold X if you want to boot Original BIOS instead ³
³ - Hold Y if you want to boot Original BIOS with region-free hack ³
³ - Don't hold any button if you want to run DVD-R :-) ³
³ ³
³ - "PLEASE WAIT" should appear. then "SWAP DISC NOW!" and the GC ³
³ disc is stopped (and laser off). As soon as you see the disc is ³
³ slowing down it's safe to remove the original disc and put your ³
³ DVD-R instead. After a few seconds the drive will start to spin ³
³ again and disc will boot (if you didn't have enough time to do the ³
³ swap trick, turn off the GC and try again) ³
³ ³
³ - Remove the top of your GC if you want to use full-size DVD-R ³
³ ³
³ THE MEDIA ³
³ ³
³ The GC drive only eats DVD-R, MINI-DVD-R and single-layer silver DVD, ³
³ it doesn't work with + media or DL at all. ³
³ But, like Xbox thomson drive, it is very "sensitive" to the brand of ³
³ media you're using. Some are working better than others, some even ³
³ NOT AT ALL! So better check what media other users recommend. ³
³ ³
³ After a few tests here is what we think: ³
³ ³
³ - For DVD-R, most media are working, except some cheap no-names. On ³
³ some drives only the best media is working really fine. ³
³ ³
³ - BUT FOR MINI-DVD-R it's more tricky. We tested the following brand: ³
³ SONY DVD-R 1.4GB handycam: doesn't work ³
³ TDK DVD-R 1.4GB scratchproof: doesn't work ³
³ MAXELL DVD-R 1.4GB: sometime boots, but then loose sync ³
³ DATAWRITE DVD-R 1.4GB: on some drives it works 100% like the ³
³ best DVD-R, but on some other drives it just can't sync ³
³ (when it does its working perfectly) ³
³ ³
³ In fact, we have some idea on how to improve the compatibility with ³
³ bad media in our next BIOS. For now we really suggest you to find ³
³ a good full-size DVD-R media, and get the opinion of other users. 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 (we use Nero). ³
³ ³
³ Maybe different burners will lead to different results too, for now we ³
³ just tried a cheap NEC burner. ³
³ ³
³ ³
³ TROOBLESHOOTING ³
³ ³
³ REMEMBER, THIS IS A PROOF-OF-CONCEPT-VERSION ! ³
³ There are probably lots of bugs we need to fix including: ³
³ ³
³ - Sometime the "SWAP DISC" message doesn't appear (or disc doesn't ³
³ slow down/laser is still on). If this happen to you just turn off ³
³ your GC and try again (ok, this is clearly our fault :-) ³
³ ³
³ - If sometimes after you swapped a disc there is a sync problem with ³
³ the DVD-R and origial BIOS is not loading, then try again. If this ³
³ happen very often, then you need a better media. ³
³ ³
³ - If the drive becomes idle for a couple of minutes, depending on the ³
³ media you're using it might loose sync, and hang. This is also a ³
³ bug of ours we will track. For now, if this happens to you, avoid ³
³ "PAUSE MODE" in games. ³
³ ³
³ - Audio Streaming doesn't work. So, the games/programs using the ³
³ special streaming commands will work, but instead of a nice MUSIC ³
³ you'll hear annoying NOISE :-). We'll have a look at those issues as ³
³ well ! ³
³ ³
³ - Doesn't work with multi-discs games yet ³
³ ³
³ REMEMBER, THIS IS A PROOF-OF-CONCEPT-VERSION ! All those problem ³
³ could be fixed in a next update, except for media maybe (if someone ³
³ wants to try laser tweaking we'd be interested by the results!) ³
³ ³
³ Note that on screen there's a two digit number corresponding to your ³
³ GC version (right after the Cobra Version). Here are the current ³
³ versions we support: 14,16,18,24,26,28,34,36,38,44,46,48. If you have ³
³ another version, then we don't know about it yet... 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. ³
³ ³
³ THE FUTURE ³
³ ³
³ Apart from fixing the current bugs, we have plans to make a (better ³
³ looking) real GUI, and some other surprises :-) ³
³ ³
³ For coders it's a bit(!) annoying to burn DVD-R for each test. We'll ³
³ try to work on a better solution (either using BBA or viper debug ³
³ IO) ³
³ ³
³ CLOSING WORDS ³
³ ³
³ Special thanks to E*Flash for his help, and RoM for the early units. ³

³ ³
³ That's it for this NFO, hope we didn't missed some important point. ³

³ Have a nice day :-) ³

Ok....stupid question here, is this for the PS2, or GameCube? :unsure:

*Edit* 1,400 posts! :01:

GC = Gamecube ;)

Yes, I know :rolleyes: But seeing that the site is a PS2 site, I wasn't for sure.
