That leaves the old 68k addressing problems...

are you sure about that?
it seems that always load into st ram
try it with 4mb st-ram
CiH wrote:Good point. That will have to keep until later as I'm closed down for tonight. My configuration on CT2 is 14mb ST Ram and 64mb Fastram. I guess yours is 4mb and 20mb respectively?
dml wrote:On a 68040 with FastRam + I/D caches enabled I get 3 bombs and a corrupt screen.
However, trying again with both caches disabled, it seems to run. Not bad!
I checked the PRG flags and the FastRAM bits seem to be set already, is that correct? (not looked at this in years so I could get that wrong)
Trying again with D cache enabled, still works.
This is not terribly surprising - the 040 has a big instruction cache and if copyback mode is on, it needs pushed back to ram (instead of just clearing it). Or it may not have been cleared properly after SMC.
In any case FastRAM doesn't seem to be a problem here.
My 68040 MMU driver is a bit tricky though and maps the FastRam to exactly 16MB onwards - not sure where the MS board puts it...
CiH wrote:The news from my end is mixed, but better than some have been reporting
Centurbo 2, in 'TOS 7.0' mode, with Fastram enabled, works!
A screengrab is enclosed. The CT2 prefers a VGA display, as SCART/RGB seems to hit an unobtainable video frequency and I get a 'no signal' message. The program is still able to 'esc-exit' back to the desktop. This issue with RGB and CT2 is not uncommon, and can be found also with the game 'Running', which also needs a VGA screen, so this is not an issue with anything you've done.

What actually happens when you start it under Mint?
simonsunnyboy wrote:The TOS file simply terminated, it showed the output and terminated. Maybe the main proces waiting to be launched with SPACE is loaded into memory but does not receive the SPACEBAR pressing event. In any way RAM is pretty cramped then (NVDI, some ACCs, Teradesk, TOS2WIn loaded) so from 14MB only 7 or 8 are left IIRC. Maybe this is just too small for the game to fit.

Anima wrote:However, I think it could have something to do with the sprite code compilation and I can try to clear the I-cache after each sprite compiling process.

That is possible. I'll check it more closely later on.
