Hi guys! Until now, I really could optimize my games so they fit into 128 bytes of RAM, but with my on going strategy game I found it really impossible to fit the data of 88 tiles (at least 3 bit for one tile, so in the end, that cost 33 bytes) with all the other stuff (Population, Money, etc) and the Batari Basic variables. So I decided to use SARA for extra 128 bytes. The game would be uniqe because of the support of Amiga and ST Mouse / Trackball
This would be super, making easier to flicker the sprites those are in one row and storing the data of the building / ship that is on that tile!
The problem is, that we (myself and my hardware supporters ) couldn't find any decent and affordable solution for SARA. I mean you can buy some of the original chips (CO20231 part code) for circa 16 USD, but that would really add the final price of the actual cartridges and you can't really find SARA in a bigger ammount (or I just don't have the best connections).
So my question is, have you found any good substitute for SARA and a solution for adding extra RAM to the cartridge?
