No worries, I figured it was a glitch of some sort and a honest mistake.

Sorry for the confusion - since the GG ROM has the same exact name as the SMS ROM (it even uses the .sms extension instead of .gg), and the GG versions runs in SMS mode, I have incorrectly assumed they're the same byte for byte. Now that I've verified the checksum, that is clearly not the case. I should have known better, even the Sega Retro lists different checksums for SMS and GG ROMs. It's definitely far outside my expertise to tell what exactly differs between these ROMs, but judging from what you say there isn't anything that affects the gameplay.

I was thinking about some updates to the submission rules, and here's a few of my thoughts:

• NES Red and PAL revisions have a built-in soft reset combo (A + B + Select + Start). Should it be allowed to start the run from a such soft reset? I think as a rule of thumb soft resets aren't allowed, but wanted to ask just to be sure.

• Should we restrict NES PAL version runs to be allowed only at 50FPS? The thing is, while this revision was released only in PAL regions back in the day, it's apparently also present on the recently released Evercade handheld console, and I can only assume it's being ran at 60FPS. Not that I expect anyone doing speedruns on Evercade, but wanted to ask just in case.

• And then there are SMS and GG versions... the thing is, there doesn't really seem to exist a Game Gear ROM of this game. Fantastic Dizzy is one of the few games that actually run the exact same Master System version on a Game Gear (with the SMS video output downscaled do GG's resolution). This begs a question - is there really a point in having separate SMS/GG categories then? There is just one caveat that I can see. The SMS cartridge was released only in PAL regions, thus one might argue we should restrict speedrun entries to those ran at 50FPS. However, AFAIK Game Gear runs at 60FPS regardless of region. So, that would put anyone playing on a PAL Master System at a disadvantage, since the game runs 1/6 slower on PAL. Or we could just allow playing on NTSC SMS consoles, despite the game not being released in this region.
