A virtual computer that runs on a fantasy console. I find this very interesting, so I've made it work for now.

These can also be changed in key.lua if necessary.

- Minor bug fixes
- Modified to load ROMs as external pod files by drag and drop (Thank you pancelor!)
- Change display from full screen to windowed (to drop the ROM)
How to create a "rom" pod.
store(filepath, userdata("u8", bytelength, romdata))
Specifically, it looks like this.
store("/logo.pod", userdata("u8", 132, "00e0a22a600c6108d01f7009a239d01fa2487008d01f7004a257d01f7008a266d01f7008a275d01f1228ff00ff003c003c003c003c00ff00ffff00ff0038003f003f003800ff00ff8000e000e00080008000e000e00080f800fc003e003f003b003900f800f8030007000f00bf00fb00f300e30043e505e2008507810180028007e106e7"))
hey, this is cool! I made a CHIP-8 game and its fun to see it running here :)
Here's a test suite that was incredibly helpful while I was making an emulator, it turned up all sorts of tiny edge cases I wasn't handling quite right. you should check it out: https://github.com/Timendus/chip8-test-suite
also, if you'd like to support drag-and-drop to load ROMs, something like this should work:
on_event("drop_items",function(msg)
local item = msg.items[1]
if item and item.pod_type=="file_reference" then
local str = fetch(item.fullpath)
local romdata = userdata("u8",#str/2,str)
-- todo load romdata somehow
end
end) |
Thanks for your comments and the info on fixing the bug.
And now I can drop and load ROMs.
This is my first time using it and it's great!
The test suite also passed.
Does anyone else think a fully featured Atari-2600 emulator is possible in Picotron? (Neat meta-fantasy console btw.)
I think it is possible to emulate the CPU.Rather, I think the part that reproduces the blurring on the screen is impressive.
I have never used the Atari 2600, so I can't say for sure, but it's possible. I think.
Very interesting.
