I haven't thoroughly tested my Katakis version since last time (I wanted to check specifically for the problems I mentioned), but I died too early
The sprite bug in the fish boss is not there however (the one time I tried the version from your pack it had a broken sprite in the lower mouth area)
Anyhow, it's in M2I format, maybe not the best format to use?
I'd be happy to help to get a even bigger better collection done (Still looking for a Bionic Commando, that manages to load stage 3 *hinthingnudgenudgeknowwhatimean*)
What I'm wondering, is there actually a difference between SD2IEC versions? I've got the Evo one, with the latest firmware patch, which should allow MM and ZakMcKracken.
