rj1307 Posted August 15, 2020 Share Posted August 15, 2020 Hi, I wanted to present to you my version of the Atari 7800 SD cartridge. What you can see in the photos is a prototype version on which I learn how to use. The cartridge will be operated using four buttons and the display, of course, it will be in the housing. For correct configuration, the cartridge uses .a78 files and the header. As of today, it supports 4k, 8k, 16k, 32k, 48k files - without banking, 64k, 128k, 256k, 512k with banking. In addition, 16k RAM for $ 4000 and POKEY for $ 4000 and $ 0450. Various combinations are possible. Also supports Absolute and Activision. Below is some evidence that I am writing the truth: Demo Multi-Lock On, 512k + Pokey $4000 Demo 1E78, 128k + RAM Double Dragon, 128k, Activision F18-Hornet, 128k, Absolute E.X.O, 256k + RAM Donkey Kong XM, 144k + POKEY $0450 Bentley Bear's Crystal Quest, 144k + POKEY $4000 or $0450 Rescue on Fractalus, 32k + RAM. Can you confirm that the graphics are displayed correctly? The lower bands are due to the fact that the game is NTSC and I run it in PAL. Ultimately, the cartridge will also have a USB connector that will allow you to load files directly from a computer. I've already tested it and it worked. I'll be back from vacation in two weeks, I'll spend a few more days testing with different files and designing the final version. If you have any suggestions or ideas, please write. And there is also a sticker on the cartridge, designed by a colleague of MotionRide: 46 Quote Link to comment Share on other sites More sharing options...
