I have placed a program that reproduces the bug in Fighter's Ragnarok below.
The screen collapses on the unmodified OCM, but not on the real MSX.
It does not collapse on the modified OCM.

Fixed an issue where the screen display collapses in Fighter's Ragnarok.

Great! Fighter Ragnarok was one of the few games with problems in Zemmix Neo. Let's hope that KdL can apply this fix in the OCM / Zemmix firmware ;)

At the request of KdL, we worked on fixing this bug.
I believe he will surely incorporate it into OCM-PLD 3.9. ;)

(in a URL you can use %27 in place of ' to make the bulletin board happy)

Thanks! :D

HRA or KdL, maybe one pf you knows this. This week I tried SFG on SX-2. First the clone by RBSC but then also the real one using a UCN-01 converter. The machine does not boot and there is a noise from the audio out that slow increases in amplitude. I have not verified what SFG does on OCM or Zemmix Neo (those were tucked away). Is this a known issue for OCM in general?

@sdsnatcher73 Is your SX-2 booting in 3.58 MHz mode or with a higher clock speed? Unlike the turboR the OCM core doesn’t respect the standard bus timings and bus clock in its turbo modes, and the SFG doesn’t like that.

The problem you have experienced is in the wrong management of the RESET signal but know that I have rewritten all the code and it will be available in OCM-PLD v3.9 soon. So for the moment, when you use that cartridge, you just have to press the reset button manually or if that still doesn't work, send me an email privately to receive a prerelease of OCM-PLD v3.9 for SX-2.

With the help of HRA! we are solving several issues: Fighter's Ragnarok bug that persisted for 15 years was also present in Sunrise games like Pumpkin Adventure III, The Lost World and others. So from the next firmware also the Sunrise games will be able to start correctly.
