Space Invaders (1978) with Debugger
-----------------------------------
The [PC8080](/modules/pc8080/) machine below is configured to run [Space Invaders](/devices/pc8080/machine/invaders/)
with a Control Panel and Debugger. It is currently playable only in desktop browsers and uses the following hard-coded
key mappings:
- 1: One Player
- 2: Two Player
- 3: Insert Coin
- A: Move Left
- D: Move Right
- L: Fire Missile
Click the "Run" button when you're ready to start the simulation.

grep -E "[0-9]+ [0-9A-D]+.*;;" VT100.lst | sed -E "s/ *[0-9]+ ([0-9A-F]+).*;(;.*)/ \1 . \2/" > VT100.map
filedump --file=VT100.bin --format=bytes --output=VT100.json --comments --overwrite
You can omit `--comments` to reduce the size of the [VT100.json](VT100.json) file.
Some [VT100.asm](VT100.asm) clean-up remains, because there are still chunks of data that were incorrectly disassembled as code.
From a reassembly standpoint, it doesn't matter too much, because such instructions get reassembled into the same original binary
patterns, but from a readability standpoint, it's a nuisance.
