leandro Posté(e) le 16 décembre 2004 Posté(e) le 16 décembre 2004 - 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 You are free to redistribute this package as long as it's not changed, ³ ³ patched, ported, or whatever. ³ ³ ³ ³ Our code is free of any copyrighted code from third party. ³ ³ It is also free of any GPL licensed code, we have strong respect for ³ ³ other people's hard work. We only ask you to show similar respect ³ ³ toward our work. To put it in other words, if you are in the "right" ³ ³ side, draw the line between learning and stealing. Thank you. ³ ³ ³ ³ That's it for this NFO, hope we didn't missed some important point. ³ ³ ³ ³ Have a nice day :-) ³ ³ ³ ³ ° ° ° ³ ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ ±² ÄÄÄÄÄÄ ±² ÄÄÄÄÄÄÄÄÄÄ ±² ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´ ³ °ÛßÜÜ °Ûßß ÜÛßß ²Ûß ßßÜ ²Û °ÜßÛ °Ü Û ²ÛßÛ °Ûßß ³ ³ ÛÛ Û Û ÛÛß ÛÛ Û ÛÛ ²ÛßÛ ÛÛ ÛÛ Ü ÛÛ Û ÛÛ Û ÛÛß ³ ³X ° ± ² Û ²Û ² Û ßÛ²Û ÛÛ ² ßÛ²± ßÛÛ² ßÛÜ ßÛ²Û ßÛ²Û ÛÛ²ß ßÛ²Û Û ² ± ° X³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
