hey thanks for reading, theres a guy with an old crt monitor on one of those old advance mame cabinets and the monitor actually has a good picture, so i became nostalgic and wanted to buy it from him in order to build a pacman or dk multi cab. Its been so long and after searching for so long, i saw that 15khz soft might work under windows 7, (i dont like xp anymore) some say it does not work, then i found another tool ,emudriver that works with groovy mame or windows too, that looks promising, but to be honest , i fell in love with recalbox and its simplicity, but i do believe retroarch wont support 15khz, so i guess i would be stuck with hyperspin. Anyway , i do actually have a hyperspin setup that i can easy copy and paste to a new build i just would like to know, what would be the best option to make this happen, but if is posible to make it happen on recalbox (on pc) that would be way better, hope i explained myself, thanks for your help.
