I did the "last injector" years ago, and some more games were added to the "possible injectable games" however, according with the new compression/and/or/AES encription (different per Game) it was not possible to use it for a 4°th generación of injected NeoGeo games. (There is an old thread where i asked about aes encription and some experts out of the forum couldnt find a solution, moreover it wasnt interesing for them... Like a waste of time...)
All possible injected games (as far as I tested years ago with 3th generation) are posted somewhere (google).
Now im very short of time, however i will try to find the latest tools pack next week.
