In fact the available memory for MAME in the WIZ is only 26 MB (10 MB in the Linux area and 16 MB in the upper area)... Not enough memory to play Pulstar or Metal Slug 2 (they need about 32 MB of RAM only to load the ROMs...).

It runs like a charm, Notaz :) Maybe a 10% speed improvement in MAME...

I'm not able to release the fixed version yet... After some modifications and additions the performance has decreased about 20%, probably something weird with the cache after adding new object files... :( Update: After removing from the executable an unused object, the performance has decreased...

I think I've found that, it's the pixel clock divider (bits [9:4] of DPCCLKGEN0=31c4 register, program value-1"]. They are now using divider value 23, it was 15. Fw 1.1 settings + divider of 10 + DPCHTOTAL of 357 gives something pretty close to 120Hz. Curiously I was able to push OLED to...

Oh my god! firmware 1.1.0: DPCHTOTAL=330 DPCHAEND=304 DPCVTOTAL=347 DPCVASTART=19 DPCVAEND=339 DPCCTRL0=37888 DPCCTRL1=8767 (Franxis) DPCHTOTAL=327 DPCHAEND=277 DPCVTOTAL=341 DPCVASTART=17 DPCVAEND=337 DPCCTRL0=37888 DPCCTRL1=8767 (sbock) firmware 1.0.0: DPCHTOTAL=330 DPCHAEND=304...

Thanks! Somebody with firmware 1.0.1 could also help?

Please somebody with WIZ firmware 1.0.0 and/or 1.0.1 could execute this program and tell me the contents of the generated file show_dpc_cfg.txt? http://www.talfi.net/gp32_franxis/show_dpc_cfg.zip I would need values reported in both firmwares! Thanks in advance ;) .

Only for reference the firmware 1.1.0 timing configuration is the next one: - If i don't let the gp2xmenu to start: DPCHTOTAL=330 DPCHAEND=304 DPCVTOTAL=347 DPCVASTART=19 DPCVAEND=339 DPCCTRL0=37888 DPCCTRL1=8767 - After the gp2xmenu execution: DPCHTOTAL=327 DPCHAEND=277 DPCVTOTAL=341...

I'm wrong again... DPCHTOTAL=243 gives 67 Hz and there are black pixels in the upper right part of the screen... I have not found any good value giving smooth scrolling at 60fps :( .

Yes, you are right, it is 57 fps. My measurement method was wrong. ;) DPCHTOTAL=243 gives 120 Hz and it runs ok.

I have tried to use the Exophase's VSync() function in the new firmware 1.1.0. It seems the refresh rate is exactly 50 Hz.

I have tried your VSync() function with the new firmware 1.1.0. It seems the refresh rate is exactly 50 Hz.

Personally i like the current approach, you can enable auto-run to launch MAME when the console is powered on, but then when you exit from MAME, you go to the gp2xmenu. If it is not done, MAME is launched again and again...

It runs worse than with the previous firmware. The games don't run at 60 fps. For example if you try Black Tiger or Ghosts'n Goblins and you move the character to make the background to be scrolled you will see the scroll isn't smooth, it is choppy...

MAME doesn't run correctly with the new firmware... GPH has changed something in the video synchronization and the video is choppy...

I have tried without results: DPCHTOTAL=330 DPCHTOTAL=487 DPCHTOTAL=(487*2) In fact it seems to do nothing... Nothing seems to change. But if i set dirty MLC flag: MLCCONTROLT |= BIT(3); It seems to do something weird, the image is more and more choppier with DPCHTOTAL=330, 487 or greater...

Yes i see everything choppier. MAME says frameskip=0 but i really see frameskip. How to go back to 60 Hz?

GPH losts his time instead of fixing the libraries or solving the diagonal line... :huh:

I have just updated without problems. I have also tried the MAME4ALL autorun, and it runs correctly.
