I found a good way of testing the kickstart roms for PSPUAE.
I've got loads of kick31.rom variations but ofcourse we can only use one at a time. Also, good thing is that CPU 68020max, CHIPSET ecs, settings work for kick1.3 and 3.1.
Anyways, select kickstart 3.1 and ensure nothing is in the amiga drives. restart and see if you see a bootscreen. if not then pspuae has problems loading or using it. repeat by substituting another kick31.rom variety file. Here's my results/findings below:
Kickstart v3.1 rev 40.60 (1993)(Commodore)(CD32).rom WINUAE 1.4.6.0 NOT RECOGNISED PSPUAE BOOT SCRN
Kickstart v3.1 rev 40.63 (1993)(Commodore)(A500-A600-A2000).rom WINUAE 1.4.6.0 NOT RECOGNISED PSPUAE NO BOOT SCRN, JUST CONTINUOUS BSOD & MEMORY CARD ACCESSING
Kickstart v3.1 rev 40.68 (1993)(Commodore)(A1200).rom WINUAE 1.4.6.0 SAYS A1200 PSPUAE BOOT SCRN
Kickstart v3.1 rev 40.68 (1993)(Commodore)(A4000).rom WINUAE 1.4.6.0 SAYS A4000 PSPUAE NO BOOT SCRN, JUST CONTINUOUS BSOD & MEMORY CARD ACCESSING
* when I say WINUAE NOT RECOGNISED, I mean the ROM scanner... but haven't tested whether it would actually run...
** BOOT SCRN meaning whether I saw the boot screen or not..
*** BSOD black screen of death
