Robert

These 2 games have been added, thanks! EDIT: I've decided to put Catapult into ARCADE64 instead, where the new rom can replace the bad dump.

Send me a PM.

Welcome McHale, it's good to see you here. I'll look at the tempest set. I don't have an account at arcade-museum, so unable to download the romset.

Console hacks belong to MAMEUI. If you look in the MAMEUI repo, under hash/more, there's extra hash files (currently 229) listing more than 67,000 items that I've tested to work, and are not in the official MAME lists. You may need to do some manipulation for MAMEUI to be able to recognise these lists though. The only supported lists for HBMAME are for various neogeo things. The other unused lists come from MAME and get deleted at release time, but they keep coming back as the devs update them.

That's a known issue with sf2prime, the developer is aware of it. You have to press 9 (service) to get a credit. I don't know anything about Retroarch, nor do i provide any kind of support for it. If 9 doesn't work then you'll have to find out from them which button to use.

We've now added support for homebrew neogeo CDs. They are set up just like normal games, so you don't need to mount the CD or use software. Just start the game as if it was any other game, it starts up and runs. Added 21 titles. Although there are more CDs, they duplicate existing rom-based games, so they were left out. There's a possible bug - you might sometimes get a screen of rubbish at the start - press any key and it will then run normally. Also, some games might ask you to format a memory card - you don't need to do that, just skip past that prompt.

You're right, there's some kind of corruption there. I'll have a look. EDIT: It's fixed now. The code for history display hadn't been updated from 0.245 .

It's been supported for a few years, but remember, history.xml doesn't include games found in HBMAME.

It's supposed to be permanent, although I do sometimes make on-the-fly changes which weren't planned beforehand. Basically the "s" will be removed, unless the last character of the parent was numeric. So "dino44", or "sengoku2s01" . If there's hundreds of clones, then there could be leading zeros added, so "dino044" for example.
