- 3232Got the score 30550 in MAME.
- 4805Got the score 22250. For the first time, I played Defender on the original hardware. Ruben & Bobbie in Copenhagen has a machine, and I struggled with the button layout and got this one decent score after spending a lot of 5 DKK coins...
- 4850Got the score 26925 in MAME. Theres been quite a bit of Defender going on on the PD MAME machine. Me and Jeppe are narrowly competing for the top.
- 5063Preparing for my talk at Spilbar on 80s game music and audio technology, I looked into the audio implementation of Defender. It's basically a MC6800 that outputs 8-bit samples to a DAC. All code and data is in a 2048 byte ROM. I've now managed to disassemble and reassemble the ROM and figure out how parts of it works and even write my own replacement ROM with test sounds!
- 5094My newest Defender sound ROM plays a two-channel music loop, specifically a beepy version of the Lost Empire: Immortals theme.
- 5156This Sunday, I armed myself with a MC6800 manual and Visual Studio, and made a working Defender sound board emulator in C++. It currently only plays the boot sound, because I haven't implemented the full instruction set yet.
- 10448I found a Defender cabinet at the Brooklyn Barcade. There was a hiscore by a mysterious person 'A' (the name you get if you just press the button instead of entering your initials), and after many quarters, I started getting used to the button layout and stopped accidentally using smart bombs instead of reversing direction. I ended up with no. 1 spot of 'ALL TIME', 22,850.
- 10894I played a bit of Defender on the MiSTer, but I had trouble with the controls. I need to spend more time setting them up.
- 13535Got the score 23250. The Finnish Museum of Games arcade had a Defender machine, and I got first place in the high score list.
