The great thing about retropie is that you don't have to stick to 1 app for arcade emulation. You can choose what emulator each game uses, just make sure you have the right rom set for each emulator. For most games, mame 2003 hits the sweet spot between compatibility and speed for most games. For neo geo, FB alpha is better at that. Games like street fighter 3. Require FB alpha.

[SOLVED] Thanks to all who replied. As per info the link posted by UDb23, the simplest solution was to move all the roms into the 'arcade' directory. That way, lr-fbalpha is selectable, alongside lr-mame2003. Brilliant!

@barbudreadmon Thanks, that sounds great. I'll test it today or in the next days. My Pi is doing the update from source right now, but I don't know yet if I'll have the time to test it later today.

AFAIK there should be no need of different mouse devices for trackball/spinner/lightgun, because they all use the same /dev/input/event… devices. (Multiple mouse devices may be needed for games with multiple mouse-type devices, though.)

Trackballs and lightguns will use both axes of a mouse device, whereas spinners will use only one axis per spinner. For two spinners, that may be X and Y of a single mouse device if they are connected that way. Others, like the USB adapters that come with the SpinTrak spinners, will map them as separate mouse devices and only use their X axes.

https://retropie.org.uk/docs/Spinners,-Trackballs,-Lightguns,-and-other-Mouse-Devices/ describes the different kinds of axis mappings in great detail.

I'm back again trying to scrape MAME. Using the options available in the latest version of USX I'm still getting a simple gamelist without all the extra bits. Has the database been updated any with the information on clones/etc yet? I know you said this was in the works before, but this thread is 8 months old and I thought maybe SOME progress has been made...

I figured out my problem. I had set the video driver to dispmanx to reduce input lag on the nes. However video rotation does not work with this video driver. Thanks again for your help.

@d8thstar said in Last bits needed and then I'm done!:

doesn't look right.

please use proper code block formatting and descriptive post titles :)

@SlowSL MAME GUI seems to generate additve "OR" keymaps while you remain on that line for input. If I want to remap a control, I simply move up or down to the next one, then back to the one I want to edit and remap. This always replaces what is there starting with a fresh mapping. If you just keep pressing ENTER on the same line they combine (as you noticed).

Sometimes, I will combine stuff intentionally. For example, I might combine coin drops when playing from the vertical ends of my cabinet (3-sided cocktail design). I might also map multiple action buttons for a game to give the player the option to hit one button or another button for the same function.

Understanding the "null" mapping in per-rom .cfg files is also really useful, as it blocks the retropad mapping and allows just the raw key inputs to reach the MAME GUI. This is necessary if you want to do complex boolean mapping (with "NOT" settings for example to setup a tankstick).

Wow, well played @R1n0X and @meleu! Great scores :)

@Lyle_JP thanks for this. Never heard of it. My nieces will love this.

@rainel said in KOF 98 on @Retropie 4.1 help??:

weird that i download the single rom from some popular website but doesn't work

It's not wierd. Downloading single roms is like trying to find a needle in a haystack. How do you know which version you are downloading? If it was not a 0.78 rom, like the one you grabbed, it will not work.

@jayram1408 Swearing / personal insults on the forum as your first post. Well done.

Might be able to do better if I can save the 2nd resurrection potion for a bit longer. I also should NOT have upgraded to the Balkan gun, as the old laser can hit the tails of the flaming claw snake things even through the segments, but the Balkan gun shells are stopped.

Once you get through the regular round on lvl 8, the bosses on 8 and 9 are really easy. The regular round on 10 is all space stuff from Hyperdyne SideArms and will end you if you don't have a LOT of health to smart bomb stuff with, or a 2nd player's aux gun to block more fire.

@Lyle_JP
But the MAME files have a well defined and unique filename, as far as I know. So hashing would not be needed. You could say the filename itself is the hash.

@BuZz
Oh, thanks for the info!

Seems like this is just a bad time for scraping MAME. I am hoping that it is getting better soon! Summoning Sselph for the rescue! ;)

@Dochartaigh not that I know of.

As I'm going through the ROWs of the past and putting my input and screenshots into them, I've come across one of my nemeses, Kung Fu Master. I have a rep for mastering games quickly, but this game is a critical hit in my Achilles Heel. No matter what I do, I can never get very far in that game. Being a hard game in general is no excuse, I usually learn to destroy hard games even more so than others. I just never got this one.

@red2blue, @papinist I think I found something at http://smartretro.co.uk/forums/viewtopic.php?f=3&t=8288

This is the direct link, just in case...

Sorry, thanks, fixed.
