MAME can be the worse with this as there's no way of changing the background colour (A lot of palettes have black for the background colour, which annoys any sprite ripper) and WinKawaks sadly lacks any support for Konami games which would make ripping easier. It takes a lot of work but the end result is definitely worth it. OmegaMrKrab444 Ripping arcade sprites can be tedious especially with the built-in tile viewers.
6:For objects, simply copy and paste the objects over the objects on the original chipset (it will be on the right side of the chipset) then change the bg color to whatever the transparency color is. *HELP* it works if you copy and paste a tile from the original chipset into the 2nd paint file because it will give you a sense of how big the tiles should be. 5:Now copy and paste every tile from your second paint file (the game you wanna rip) Onto the other chipset. 4:open up a new paint file and paste your screen onto the second paint file. This way layers won't be blocking certain tiles that you would only get if objects weren't on them, or remove flooring thats under the objects. Now you can press the number buttons (1-9 i think: For snes9X no znes.Well I'm not sure if znes can do it but w.e) and it will remove certain background tiles. 2:Now open your rom, whatever game your in and walk to the area in which you would like to rip the tiles from. If you wanna rip a CPS-1, CPS-2 or NEO-GEO games, try to use Kawaks, Nebula, Final Burn or any other emulator, it will be easier. aka the bg color is transparent and all that.*P.S* I find paint works the best because it gets everything from from the very last pixel straight up. I will show some ways to do it, each one has its advantages and disvantages. Make sure that chipset works on rpg maker. This is how I do it: 1:Open up a random chipset with paint.
