@Chilly Willy : answer in GLide32X topic ;)

From SuperVDP topic : If you're writing words, remember a framebuffer will be 32000 writes for 256 color mode, and 64000 words for 15 bit mode. So 256 color mode is easy to keep going 60 Hz, but 15 bit mode consumes a considerable amount of bus time. Much of the CPU would be devoted soley to writing...

76k writes / frame = 23 MHz / 60fps / 5cycles/writes

Did you know the community RenesasRulz.com ?
Some ressources (but little about our beloved machines)

Yet, that would make sense.

... thank you ?

OK, so, I think I've got a problem. Here's my code : dc.l $01000000 ; Initial SSP dc.l $3F0 ; Initial PC dc.l $880200 ; Bus error (2) dc.l $880206 ; Address error (3) dc.l $88020C ; Illegal Instruction (4) dc.l $880212 ; Divide by 0 (5) dc.l $880218 ; CHK Instruction (6) dc.l $88021E ; TRAPV Instruc...

Looks amazing !

Hi you all. I wan't to ask you how the 68k handled the Interrupt Process with the 32X, but I think I've found by myself. Thus, here's how I understand it. A custom ROM in the 32X (you know, the 32X_G_BIOS.BIN) masks the 0h-100h from the cartrdige ROM. This custom ROM reads : 00h 0088 0200h 04h 0088 ...

Great. Indeed. Thank you Jorge !!!

Chilly, just to let us know, what framerate do you achieve on emulators ?
