Using 0.236 (version from arcade.mameworld.info) and 30 Test gives an "error parsing cheat expression" message and then it runs normally. That expression is mentioned only a few times on Google, and checking within the last year gets no hits. I don't know if this is known already but I'm m...

This Model 2 game was marked as working recently but it really isn't because after the 1st course the graphics go all glitchy. You can still finish the race but it's very hard to come in 1st place when the track disappears. However, there's an original arcade cheat to practice the secret course Sega...

Jumping Break's update/sequel, Poosho Poosho, is actually smaller by several hundred K's than the original, plus it has "infinite lives" cheats while both sets of Jumping Break have none. Odd but good to know for those who want to try these games.

Anyone know what if any changes there are to the USA Version of this Kaneko game? Many years later Kaneko released their 1000 Miles Rally games in USA versions which added cars and improved graphics and so forth, but I can't find any info about Heavy Unit. Was it just a title change or is it better ...

I see that the Baby Boomer version of T.P. is the only one that has a PAL dumped (pal10l8.u1d) and I'd like to know what exactly this does and does it have any effect on gameplay?

Now this is weird. Captain Zodiac is a 1993 Taito game I never noticed before, even though the Japan set was in 0.200 and the World set in 0.211. It's a punching game which has no screens emulated because the display is LCD, so it's marked as not working. However, the ARCADE version of MAME I use, w...

I saw a flyer for Space Beam that says Nanao made this game. I saw no mention of Irem. Who actually made it? There's no mention of Nanao anywhere in the m10.cpp driver, but Wikipedia's Irem page says they developed Meikyuujima (also known as Kickle Cubicle), but there's no mention of them having any...

I saw there was another early Irem game, PT Reach Mahjong, that has its own driver, m14.cpp. Turns out it's a ball & paddle Breakout-type game! It's all in Japanese because there's no way they were going to export something like this. Sadly, there's no sound unless you have the ptrmj samples, wh...

I was trying all the games in the m10.cpp driver. Andromeda SS is not working because of an incomplete dump (the aliens appear but not your ship), but the other games are OK. However, only IPM Invader has imperfect sound while the other games' sounds are completely unemulated. They do have sounds if...

I noticed on HG101 there's a listing for GameTech - Tetris Fighter from 1995, not to be confused with Tetris Fighters from 2001, which is in MAME. Please someone dump this game (if it exists)! Another game by the creator of Master's Fury must be found!
