@Dandy:
I check my (UAE) Setup where I test my things
Library Version/Release/Compilation Date is the same. Mapparium does not use any "additional" MUI Classes so I guess this should not be the problem.
(I never used MUI4 on classic Hardware, I use and test against 3.8 only on UAE and classic hardware (A1200), but the same code does work on MOS/AOS4, so I would assume it should work also with MUI4)
did you try an other Program like ColorIt or FPCMines from
http://blog.alb42.de/fpc-amigaaros-m68k/?? if they work it should not be something with MUI (they use the same way for operating MUI classes) But this programs does not need a GFX card, (run fine with AGA 32 Colors, on my real A1200)
@kolla:
Does not make sense to make a non-FPU version, it has to calculate floating point Values with rather high precision. Softfloat is possible but VERY slow and it's nearly to slow already for a 68060 processor. On a 68030 (the last one without FPU) it will be definitly too slow to use.
