I've had the NeoSD MVS for a while now, and from day one I was experiencing the reset issues, which were supposedly caused by insufficient power supplied to the unit. I could, however, still run the games fine, as ling as I flashed them onto the cartridge and took the microSD out, disabling the menu hotkeys, etc.
While this was fixed in the update sent to me by the NeoSD team, I have one issue remaining [well, two actually, but we'll come to that]. I can't get Shock Troopers 2 to work. The issue applies to Lansquenet 2004 as well, which is a ST2 hack.
My setup is as follows: MV1-FZ without any modifications except for Universe Bios 2.0, PC power supply, Vogatek supergun MKIV and a ToToTek converter for PlayStation controllers.
Every other game works fine, as far as I can tell, especially now, when the reset loop is no longer an issue, except for Shock Troopers 2. After the Neo Geo boot up animation, I get an error screen from the Uni Bios exception handler:

NeoSD team has confirmed that as far as they know, I'm the only one having this issue, which makes me wonder if the Uni Bios is at fault here.
I haven't tested the game on the original bios, but I'm planning to, unless someone is still stuck on 2.0, ideally with an MV1-FZ. That's issue one.
Issue number two is MOTW. I remember playing through the game before the NeoSD cartridge update, and I don't remember any issues. Now however, the game throws the error screen at me after a few rounds. The current stage music keeps playing, but I get white text on black background, not unlike the warning that software is not for use outside of country XXX, which says the game is designed to run on original hardware.
It would seem that game's protection is kicking in, refusing to run from a different board. I could swear it was running fine before. Any thoughts or solutions would be appreciated.
