    David, I ran a test with Interbank Incident and it is not sufficient to change the $FF03 routine which is within ibi. See $21A0 leax >L21b2,pcr os9 F$Icpt pshs cc orcc #$50 lda #$35 sta >$FF03 puls cc,pc L21B2 cmpb #$02 beq L21BB cmpb #$03 beq L21BB clrb L21BB stb <u0013,u rti You would think that since NOPing out the sta $FF03 in Cavewalker let the program run under NitrOS-9, the same thing ought to work with Interbank Incident. I have not tried any of the other Level1 V2 games you mentioned. R...

He looked at the trace log from MAME's debugger and saw NitrOS-9 got stuck in some form of loop and just kept looping. So he looked at what disassembly files I sent him and saw something interesting. He saw that Cave was writing to FF03.Looks like it enables VSYNC PIA IRQ? Curtis had me use DED and did these steps. Used DED and skip to $D Then go to on screen to $0D You should see $B7FF03 Just for a test Curtis had...

    David Ladd wrote: Robert, Right and you are using VCC. Using VCC and NitrOS-9 L2 and CaveWalker does work, BUT here is the BUT....It does not work on real hardware. I have tested this as Barry brought this up to me. We have already proven that VCC does not emulate the CoCo3 completely right. So if you happen to have a real CoCo 3 to test on please try your test on real hardware. David, You are correct. While the Level1 V2 Cavewalker runs on MAME/MESS when booted from the game disk, I can't boot Level2...

    Just ran another test using VCC with NitrOS-9 L2 V3.3.0 installed on a VCC hard drive. The hard drive boots to an 80-col Window. I have a command to check for the first available window, convert it to a vdg type, and start a shell. There is a GAMES/CAVEWALKER directory on the hard drive. Cave was edited so that /TERM was changed from $54,45,53,4D,CD to $57,B1 ie /W1 My command vdg converted /W1 to a vdg type window and started a shell in it. I switched over from /TERM to /W1 and then entered cd games/cavewalker...

I do not have a copy of Biosphere, but I was able to test Interbank Incident and it would not run under NitrOS-9 L2 either. Yet works fine on OS-9 L2. So yes there is a issue.
