Make Sufami Turbo .ST rom files compliant with Snes9x core

[KingKebab]

Hello,

Like many people, I use .dat files from the No-Intro group to manage and validate my roms. Also, I use zipped roms to reduce their storage size.

In RetroArch, I use the Snes9x 1.60 core with Super NES, Satellaview and Sufami Turbo roms. Any roms works great except with Sufami roms.

When I load zipped Sufami roms I get an error message about the rom extraction. Here is the error I get in the log file :

libretro INFO] "x_\z_____C______Byd__N" [bad checksum] LoROM, Corrupt, ROM+RAM+BAT, NTSC, SRAM:Corrupt, ID:___G, CRC32:46F16E00
[INFO] [Environ]: SET_PIXEL_FORMAT: RGB565.
[INFO] [CONTENT LOAD]: Failed to extract content from compressed file: C:\Users\Beloko\Downloads\RetroArch\roms\sufami\Bishoujo Senshi Sailor Moon Sailor Stars - Fuwafuwa Panic 2 (Japan).zip

So, I did some tests and it seems the issue come from the rom file name. Because the .ST extension isn't entitled in the snes9x libretro.

To fix the issue, if I rename the rom file into .SFC (or .BS) instead of .ST in the zip archive file then the game starts and runs properly. There's no bad checksum message anymore.

[libretro INFO] "ADD-ON BASE CASSETE" [no checksum] LoROM, N/A, ROM, NTSC, SRAM:128Kbits, ID:A9PJ, CRC32:9B4CA911
[INFO] [Environ]: SET_PIXEL_FORMAT: RGB565.
[INFO] [SRAM]: Skipping SRAM load..

[INFO] [Cheats]: Load game-specific cheatfile: C:\Users\Beloko\Downloads\RetroArch\cheats\Snes9x\Bishoujo Senshi Sailor Moon Sailor Stars - Fuwafuwa Panic 2 (Japan).cht

So I suggest to add the .ST suffix as compliant in snes9x libretro to make No-Intro's Sufami romset ready to play for everyone.

It probably just needs it added here: https://github.com/libretro/libretro-super/blob/master/dist/info/snes9x_libretro.info#L6 Can you make that change to your core info file locally and see if that fixes it for you?

Hello HizzleKizzle ,

I updated the supported_extensions value in my local config file \RetroArch\info\snes9x_libretro.info like this : supported_extensions = "smc|sfc|swc|fig|bs|st"

But unfortunately it doesn't make the .ST compliant. I get the same error in the log file and the game doesn't play. However uncompressed .ST files appear in the RetroArch's browser list.

It likely needs to be added to the extension list in libretro.cpp. I'll test a build.

PRs open, works fine with those adjustments in place.

Hello Sanaki,

Thank you for your fix. Hope it will be merged and available in the next core release. If you like, I can test with RetroArch too. But I'll just need the bin files to replace.
