gsu (superfx) support [work in progress]

[woozle]

Just tried the new firmware and Star Fox crashed during the first level, audio kept playing but the game screen was stuck on a frame. No graphical glitches, it just froze.

The rom I'm using is "Star Fox (USA).sfc" in the folder "Unplayable Chip Games" from the Smokemonster rom set. Using a SNES mini with no mods other than an RGB amp.

Played the first Star Fox level again, and instead of freezing my Arwing just disappeared. I could still play the game, the camera followed my controller inputs just without rendering the Arwing. Using GSUv04 files and the SD2SNES fpgabase.bit from the GSUv02 release, should I be using a different fpgabase file?

Didn't realize another fpgabase file was provided in v03, since I skipped that release. I'll try that and update my post.

Update: Tried the newer fpgabase file from v03 and the Arwing still disappeared near the end of the level.

People, please provide with your report what console revision and region you are using, and whether you have SuperCIC installed.
Also, full rom filename, and MD5/SHA-1/CRC32 checksum of the rom.

i have a 1chip snes (us model) with super cic and a sd2snes rev.E1
all super fx games crashes within a few seconds.
i tested another another snes but its the same.

Are there any revisions I should mention for the US/NTSC SNES mini? I'm using an SD2SNES RevH from the Krikzz store, not sure about SuperCIC, is that a setting or an add-on a user installs?

Just tried playing Yoshi's Island. First level played fine, 2nd level having graphical glitches and then a black screen. Music still plays, but controller input doesn't do anything. Rom is from Smokemonster set, in the "Unplayable Chip Games" folder named "Super Mario World 2 - Yoshi's Island (Europe) (En, Fr, De)". How would I get the rom data so I can provide more useful debugging info?

Tried playing it again. 2nd level loaded fine, played for a bit and died, then when I reloaded the level it played for a few second before the same black screen/music only failure.

Update: forget about all the Yoshi's Island bugs I mentioned, as James-F pointed out I was running a pal rom on an NTSC console.

I reported similar issues a few pages back but i’m On a 2 chip pal snes, but my sd2snes is Rev.E1 I wonder if that is the issue here?

it is not the snes. i tested some models. the sd2snes rev.E1 have some issues with the gsu firmware.

the sd2snes rev.E1 have some issues with the gsu firmware ??

As I wrote the games crash after a short time, usually already in the intro after 2-5 seconds.

@woozle
You are playing pal rom on an ntsc console.
No wonder it has bugs.

Oh wow, didn't realize that. Updated my post where I mentioned the "bug". In the folder there are two Yoshi's Island roms...didn't realize I was loading the pal one. Played it again on the NTSC rom and it works fine, will probably delete that pal rom off of the SD card so this doesn't happen again.

What about for "Star Fox (USA).sfc", that's a NTSC rom right? Still has crashes.

In addition to your console info (and NTSC/PAL), the most important info to provide is what ROM you are using. Without posting the ROM's source and MD5 hash, error reports are pointless. Redguy won't be able replicate issues unless you can tell him exactly what ROM you are using.

The tool here http://www.romhacking.net/utilities/1002/ gives me the following info for the star fox rom that gave me errors (arwing disappeared in the first level but game kept playing otherwise),

No-Intro Name: Star Fox (USA)
(No-Intro version  20130701-030720)
ROM/File SHA-1: 1F5355534CCFAF26AE6C8F055F3E4768F9D72A7E
External Header: No
File/Rom Size: 1048576
ROM CRC32: 0BAE0941

Is that correct info/is any other info needed?

[SmokeMonster]

Unfortunately the DATs provided with that tool are 5 to 8 years outdated, and only work for No-Intro. So it's not going to be very useful.

But the SHA-1 you provided is exactly what is needed and allows anyone to use the exact ROM that you are testing with.
