new mame2010 folder structure

MAME art files are actually sized to the native screen resolution of the original games and most are extremely small already. From what I've seen, enabling even the smallest bezel on an old game makes a noticeable difference in performance.

@mediamogul Yeah, i've decided not to bother with the artwork. Only a couple of games actually require it to make the game playable. I know 'frogs' is one and 'gorf' was mentioned above. You can enable the side panel in Gorf in the Video Options menu but then the Aspect Ratio is wrong. If anyone knows any games in 0.139/2010 where the artwork is essential ?

lr-mame2010 is now my primary MAME emulator on the Pi 3. I haven't encountered anything that's made me wan't to go back to lr-mame2003. You can even play gun games with the joypad without the sight springing back to the center everytime! I also haven't encountered any games with performance issues, maybe i've just been lucky. Outrun is the only one I found but we have the superior Cannonball engine for that game. (And i've seen 'auto-frameskip' in the Retroarch menu for any games that have slight speed issues, if I find any).

You can solve that by correcting the aspect ratio in the core options. Also, sisnce the side panel is independent of the artwork, it can be enabled without any loss of performance.

@markwkidd I noticed in the RetroArch QuickMenu/Options the aspect ratio was set at DAR. I think this should be PAR. This then gives the correct aspect when using 2/3 screen games, Gorf can use the built-in side panel and be the correct aspect and I checked some vertical games like Bombjack and they are now the same ratio as the MAME screenshot shows.

@maxbeanz i think DAR is the correct the default. DAR = display aspect ratio. this basically means that that the game is displayed in the aspect ratio it would have appeared in the real cabinet. typically 4:3 (or 3:4, for vertical games).

PAR = pixel aspect ratio and simply maps the pixel image 1:1 to your display's resolution. this gives crisp output, but often in a nonsense aspect ratio as the pixel image aspect ratio could be quite different from how it appeared in the cabinet. eg, it makes CPS2 games (street fighter 2, etc) appear in near-widescreen; aka, 'fat ryu edition'.

if games don't look right at PAR in 2010, then something else is going on. i would have thought that standalone mame2010 would adjust the aspect ratio when artwork is turned on, but for the libretro version that may yet to be hooked up.

@dankcushions Games look the correct aspect in lr-mame2010 with PAR set (in the QuickMenu). Isn't there also a ratio setting in the RetroArch Video options ? Maybe there is a conflict.

I’m only using lr-mame2010 for one game, but I had to switch it to PAR to get the correct aspect ratio as well.

that would be a bug in mame2010, then. could someone report it, with some screenshots?

. Isn't there also a ratio setting in the RetroArch Video options ? Maybe there is a conflict.

yes, but by default it is set to 'core provided' which mean the core provides the aspect ratio information, not retroarch.

markwkidd · 16 Mar 2018, 23:03

Agreed with Dank, that sounds like a bug that I have never seen described before now.

maxbeanz · 18 Mar 2018, 17:27

Yeah, I think DAR is correct but if you play a multi-screen game (like Ninja Warriors) or enable built in artwork (Gorf side panel) then it looks squashed horizontally and you have to enable PAR. Unfortunately I couldn't get it to save a Game Override, if I change the Ratio back to DAR in another game then go back to e.g. Ninja Warriors it's still DAR. So I don't think Overrides save/work properly.
