Sorry but no, An AES system costs around 100 to 300 used. Plus, an extra 200 for a good mvs to aes converter since alot of the converters don't support all the games. Also you can ruin your system by attempting to solder in the unibios.
Also the unibios makes it where you can set it to AES on MVS cartridges.
Unibios also has a In game menu for cheats.
Debug Dipswitch support on neo geo games(this is how i posted those hitboxes for kof98).
Sound test for the games(even those with out it).
Plus quite a bit more features.
