Is official JIT is alive.

While banging my head, going round and round in circles.

I thought, why not try another rom. So I tried DIAG ROM, while the 32bit version seems not to on winuae or PSPUAEv2. I tried the 16bit rom under JIT. It booted perfectly, I was able to test everything and JIT worked prefect through out. So, as 32bit is using longwords and all roms tried are 32bit. Im currently checking I have the longword code correct.

Again, "almost there", .

Getting there slowly.

When I was at the point of starting to test.
It would give pink screen, no exception. Then progressed further to an exception, then further to another pink screen.
Now I have it booting to half way through ExecBase setting up rom stuff, then deciding something is wrong and it forces a reset, no guru though.

I know DIAGROM 16Bit, boots and works perfectly under JIT.
However it skips all the complex stuff a real rom does. So I will keep at it.
Maybe tonight I will have that breakthrough, if not, will switch back to getting menu finished, then I can start adding proper options. Been on JIT for around a week now, so will have a break from it. Be nice to play around with CD32 and CDTV, did do a test with of cdstack, in CD32 mode. Ran my compilation disc and played Microcosm.

Also want to revisit, ME Paula. As I think we should be getting alot more speed, since CPU, just says produce audio and hands ME data. ME then does everything else. Thinking of trying the ME 2MB scratchpad, so its all done locally, basically not using shared cpu memory. See if that gives us the speed I was hoping for.

Bugger me, but i'm tryng to wrap my head around this. So JIT has a sort of "fetching" problem from 32bit address space? Because the way i think the 16bit roms are just smaller in size and the machines they are used in have less address lines anyway. But the code in the ROMs are still 32bit because even A500 was kinda agnostic about that and 68000 for example was ok with 32bit coding grammar.

But sounds like fun! Do carry on
