my first HB 2600 16 in 1 cart

[ZZTOP SOFT]

I know that is not brand new, but i want to show my work.

This is my first home-brew multi-game (16 in 1) cartridge, i have to say that is very easy to do, thanks to the Atariage people who show how to put the game in a EPROM instead the original ROM.

The original concept stills, i use one 74LS14 to invert Enable signal.

My work: I use an 27C512 EPROM, A12 A13 A14 A15 are afected to LOW by the 4 switch, normaly one 10K resistor forced to "1" every adress. That way you can select 16 games(4K every).

The Next: make 8K banksw., and select a nice 16 8K games (27C1001).

Eprom and custer revange(dream come true).

 

2 more games: Pitfall y Indy500XE (mod. by gus)

 

If you don't ear about this modification before, I hope who sees this post tries to do it.
