This board is very new so I wasn't able to find a game list before I ordered, but I was already sold on the earlier Air Attack boards so I was more than happy to take the chance on this for my Galaga mod. Every time I find a new shooter on this board is like Christmas, if you love the genre you owe it to yourself to set up a dedicated cabinet for just this purpose. Here's a few flaws I found, otherwise everything else is perfect in my eyes.
1. No sound affects in 1943, 1943 Kai. Music doesn't seem to que correctly.
2. Exes Exes (Savage Bees) runs too slow. Unplayable basically.
3. Vulgus is on there twice
4. Super Contra has round slowed down to a crawl, game plays well otherwise
5. Forgot the game, but one of them has invisible walls where sprites aren't displaying correctly.
6. Space Invaders has no sound
7. Galaga is missing the ship explosion sound effect.
As you may have noticed, it's the older games that gave most of the issues, luckily the bread and butter of this collection are the 90s era shooters like DonDonPachi and Strikers 1945 and those look and sound outstanding.
Here's a few pieces of advice I have if you're doing an Arcade Iup mod for this:
1. Dont use the stock monitor from a Galaga machine. Trust me, that screen is terrible.
2. If you do use the stock screen, you need to take it out and rotate 180 degrees.
3. Turn off the first copy of Vulgus. The sound is better on the second.
4. Turn of Exes Exes.
5. Use four action buttons on your CPO. So far only one game seems to use the fourth, (DAIOH? sp?) But it's also needed in the menus.
