I've just acquired a Mattel Aquarius 16K ram cartridge but I'm not sure if it's working properly or not. When I type PRINT FRE(0) without the cartridge fitted I get 1724 (bytes - 1.7Kbytes). However, when I type the same command with the cartridge installed I get 11964, which is 11.7K. So does this mean I've only got an extra 10K instead of 16K?! Also, when I run a program to poke a value and then immediately read it from addresses 16384 to 32767, it fails to read the same value before it gets to address 32767 (the top of the memory allocated to the external 16K ram), somewhere in the mid 20000s I think. Any help gratefully received 🙂

Hey all! I got a lot done on my game today, and I feel that it's mature enough that I can make a post about it. After making a few VCS demos and such but not feeling like finishing them, I thought I'd come up with a game for the VCS I'd get passionate about. After Sprybug's awesome Sidescrolling games, I figured I'd try and make one myself, because sidescrollers are always awesome. Mine's not quite as complex as it only scrolls one way, but I figured I'd keep it simple for my first one.

Hey guys! This is my first post here but but in first place i need to thanks very much to everybody that creating this "wall". Last week i was at our local game jam with my old&good atari 2600.Topic of the jam was: seed so i created this game. Pigeon Fever is a endless platformer where player is a north korean construction site worker, who work for bowl of rice, and his main task is catching a pigeons by jumping or climbing on scaffolding. I use and tweak a bit Fake Gravity Platformer by Random Terrain http://atariage.com/forums/topic/179473-fake-gravity-platformer-test/page-3?hl=%2Bfake&do=findComment&comment=3270801 and Castle of Doom 14v by atari2600land http://atariage.com/forums/topic/216203-castle-of-doom/page-4?hl=%2Bcastle&do=findComment&comment=4184297 To be honest, I'm a type of guy who want do something and teach my self by looking into it. I was trying to read that asm book for atari with online emulator but in many times it was super hard for me and when i asked somebody, they can't even explain me in way i would undertand it. But seeing code for those project and how things works was accually helpful in someway. Now after this, i think i will spend more time with VisualBB ^_^ PigeonFever.bin
