FBA vs. MAME

UDb23

@pjft Precious info! Will try asap, thanks.

pjft

@udb23 By all means! For the sake of correctness, I am playing Gunlock, which is the EU version of the game, I think.

I'm not quite sure what romset AdvMame relies on, though, but I do have it working and tested it out yesterday before replying, going to the first stage's boss.

Isn't FBA much better for CPS3 and Neo Geo games?

AndersHP

I believe FBA is better for NeoGeo, yes. I'm running NeoGeo in FBA only.

Anyone tried DoDonPachi DaiOuJou? It's supposed to be the best 'Pachi-game out there, but it's very glitchy in FBA.

Also, I wondered if these lists are based on trial and error for every single game?

see our compatibility lists: https://docs.google.com/spreadsheets/d/1GaqIIoiWbzKHwZ52S2xCSDQXILo81Ls1mHK6czKGAtM/edit#gid=1671511927

i played it quite a bit. it has a lot of slowdown, but that's probably hardware accurate.

pjft

@andershp I had played it in the past, and it seemed to run well. I've just left it on demonstration mode for a while and it seems to consistently it 59.x-60fps.

I expect that if I play it it'll be the same.

What do you mean by "glitchy"? Also, are you referring to Master, or Black Label (and, maybe @dankcushions knows - what's the difference?)?

@pussyfoot I can share the small list of games I have that run better in AdvMame (basically anything that lags on Mame or FBA I try it there) when I have the chance to retrieve them from my Pi but the SEGA System 24 like Bonanza Bros, Crack Down and Gain Ground run flawlessly there, as well as Bubble Symphony, Bubble Memories, Darius 1 (3 screens), Darius 2 and... Gaiden, was it? RayForce. Sly Spy and Midnight Resistance don't have audio issues later in the game. Arabian Fight. Puzzle Bobble 2, 3 and 4 (I think). Nitro Ball.

I added the SEGA System 24 games. Super Masters (golf) won't start and I assume the controls on Rough Racer need analog or a spinner to work...

Let me know if those other games are worth moving over or adding.

Oh, I also use it for Outrun and Turbo Outrun as well because of the analog controls and no noticeable lag.

Yeah, and PunchOut works great, too!

Do you know how to prevent it from stretching the output to 16x9? I'd like to keep the original aspect ratio of the game.

pjft

@pussyfoot I checked and I didn't find any glaring omission there. I also have the Sega Virtual Cup (?) soccer games there, but other than that you have pretty much the majority of the games I have on AdvMame.

Alas, I am not that much of an expert in AdvMame - I'm still struggling to configure Dip Switches for OutRunners, for instance.

I too have noticed that the aspect ratio is a bit different to the one in MAME 2003. @caver01 any thoughts on this?

UDb23

@pjft great, thanks. I think I have the right rom.
Will check tomorrow and let you know.

I do. My thought is that you need to be mindful of what you mean when describing "the orignal AR of the game". For example, Street Fighter II is programmed to a very wide AR, almost like a 16:9 widescreen. However, anyone who has played the actual game knows it was displayed at 4:3. So. . . this is a game where the original resolution, as designed, is NOT how it should look when played. It should be stretched to 4:3 to make the characters and scenery not look distorted. Preserving the game's AR is not an accurate way to go in some cases.

Now, the challenge is getting AdvanceMAME to bend to your will in these cases. How do you get it to force a certain AR?? I would need to dive into the docs to find the answer, and even then, we would need to test. Sometimes, the settings in the .rc don't work like expected, although recent updates have improved this somewhat.

Have you told Advmame that you are using a widescreen with display_aspect 16/9? It might make a difference. Also, I am thinking of configs like display_expand in combination with display_magnifysize on a per-rom basis. This is going to be tricky, and we might need to ask the developer for advice here. The example being something like: "How do I force Street Fighter 2 to display 4:3 on a widescreen TV?" Now, I can't even test this since my system runs on an old LCD, but maybe AdvanceMAME already knows to add a black border if you setup your AR properly with display_aspect 16/9? You tell me?

caver01

I think I need to start working on my TV-connected project sooner than later, if for no other reason than to help folks in this situation!

pjft

@caver01 thanks for the thorough reply! I was mostly asking as you might have crossed that in the past. I get what you mean in terms of resolution vs aspect ratio, as truth be told for the most part I'm not one to be excessively picky about that.

Still I'm always keen on learning from everyone else's experiences, hence the question. Thank you!

caver01

@pjft Yeah, I have been around and around with AdvanceMAME using earlier versions like 1.2 and 1.3 on the Pi before I started using RetroPie. I spent a lot of time configuring it with custom modelines to get the display resolution right for vector games to look great, but a lot of that is unnecessary now with more recent updates. I still wish we had more direct control over the viewport like we do with RetroArch.

Updated MAME and AdvanceMAME rom lists.

AdvanceMAME: https://pastebin.com/nic0T0Gg

Notable changes: added Demon (vector game) and Toobin to AdvanceMAME. You have to edit the controls for Toobin to get it to work, but it runs great under AdvanceMAME.

If you have 8-way joysticks, or using a gamepad, I would recommend setting up a "tankstick" control mapping scheme for Toobin which allows you to control the game with a single stick as follows:

Here's a mapping for a single 8-way joystick to control two tank sticks:

Game Control           Mapped to
Right/Up               Up <not> Right     or    Left <not> Down
Right/Down             Down <not> Right   or   Right <not> Up <not> Down
Left/Up                Up <not> Left   or   Right <not> Down
Left/Down              Down <not> Left   or   Left <not> Up <not> Down

This scheme can be done using <CODE_NOT> mapping, which lets you combine controls and exclude controls for each. So, for the first one, you would open the MAME GUI menu with TAB, then modify controls for THIS GAME, then select Right/Up in the menu, then to map control push your joystick up and let it recenter and immediately right twice, and let it accept that. Then add another for Left and immediately Down twice. Once both of these are accepted, move down to the next control and repeat, double-tapping directions that you want excluded with <not>.

This gives you control with one joystick for games that normally require two. Battlezone, Vindicators, etc. can be mapped this way.

Pussyfoot

@caver01 That works great for Battlezone and Vindicators! Thanks! I couldn't get it to work well for Toobin. I think that game used 4 buttons, not two joysticks.

caver01

@pussyfoot It used four buttons with two on the left and two on right which amounts to the same as a set of two 2-directional sticks. UP or Down, for ether the left or right side.

Still, I agree, some of the control is not as intuitive as you might think for Toobin. I found playing with some of the combos helps, but I also suck at the game anyway, so it hardly matters.

pjft

One game I just tested that surprisingly performed better in MAME rather than in FBA is "The Cliffhanger - Edward Randy". In FBA it stays at 55fps or so while it runs full speed in MAME. I wonder if the emulation for the game is fine in MAME.

LinuxArcadeGuy

@pussyfoot most of those games require samples to be located in \retropie-device\bios\fba

Left/Up                Up <not> Left   or   Right <not> Down
Left/Down              Down <not> Left   or   Left <not> Up <not> Down

Can this work as a replacement for a 4-way restrictor plate in 4-way games, like Pacman and Donkey Kong, in retroarch.cfg, perhaps?
The accidental up+right or left click can really make a difference in these games, and it's quite a hassle to rotate the plate underneath every time I want to play these games...
