Hello, I extracted NES games from the Classic Games 500 in 1 (https://bootleggames.fandom.com/wiki/Classic_Games_500-in-1). Some of the games worked properly, while others did not. For the games that did not work, I downloaded replacement versions from the internet for some of them only, and then modified those games so they match the appearance and behavior of the games included in the original 500-in-1 Classic collection.

The other day, I decided to rearrange the music in the ports of arcade games Gamezone II, and I'm publishing my result.
If anyone can tell how to stop the track correctly, I would be grateful. I would also like to figure out how to change the graphics banks in Scramble from Gamezone II to make the graphics more compact.

VT03 games can be placed in a VT02 menu system (such as on the dreamGEAR 75-in-1), so I don't really know what you mean by that...it's theoretically possible for them to be VT02 back-ports, but them being the VT03 versions is more likely.

the code from the pcb:

also links a hint to VT03, however the undumped section of the Bootleggames Wiki is still wrong about "non-Waixing versions of VT03 games". Surely, there is Germ killer, but judging from the rest rather being 8-bit sounds, it is too unlikely for the pcm version.

Also: undumped section of the Bootleggames Wiki is definitely wrong about the info for the Rosen Car player having PCM WXN+YMK games, because  those suspected titles (Germ Killer, Magiccal Kitchen, Maze Puzzle, POP Monster, Under Water Rescuse, X Ball, Access Block) were not even in the console.

and one more thing: the older Wireless Baseball console by Dreamgear does NOT have the Game Maze Ball in it at all. it has X-Ball instead.

Thanks for the info 😁
