What is BLL?
BLL is a low-cost developpment-kit for the Atari-Lynx, which is completly in-official.
The BLL-project started under a different name arround 1992, when Lars de-hacked his Lynx and we started to read-out the games. In the course of the project Lars developped a SRAM-cart and a keyboard-driver, so that we were able to get a complete debugger to run on the Lynx. By this time I've also written a remote-debugger and of course Lyxass, a macro-assembler for the Lynx.
With these tools I started to write a little demo we showed of on CeBIT.
After this the first commercial project started: A driving-school-program, which wasn't the big success :(. My second project was T-Tris. I started this project mainly because there was no Tetris for the Lynx and I loved to play the old DOS-text mode Tetris. T-Tris was a living project, means everytime I learnd something new about the Lynx I tried to stuff it into T-Tris.(This is the reason why there are three different T-Tris versions ! Sorry.) Due to persistent begging to release T-Tris, Lars and I made some design-changes, added a not-before-seen-as-game-casing box and started selling T-Tris. A few months later, while working mainly on BJL I tried to put an EEPROM on our carts, and it worked. This was the start of a new release of T-Tris, as the first game ever for the Lynx with a save-game option ! (Ok, EoB had it also, but I know only one person, who actually owns one !!)
But how could we do it ??
Thanks to a simple error Atari made. As you (maybe) know, all the Atari-carts have an encrypyed
header and a check-sum over the complete rom-image. This checksum is so da?? good that changing a
Currently the total costs for the hardware are arround 40DM (including cart,EPROM,EEPROM and interface).
This is no fixed price, it may change.
