An emulator for the Uxn stack-machine, written in ANSI C.
This emulator's system device supports changing a stack's location to a page of memory. The default memory mapping is as follows:
0000-ffff, as RAM.
10000-100ff, as working stack.
10100-101ff, as return stack.
To use the last page of ram(
0xff00) to host the working stack:
#ff .System/wst DEO
The stack mapping is 254 bytes of data, a byte for the pointer and a byte for an error code.
All you need is X11.
gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/screen.c src/devices/controller.c src/devices/mouse.c src/devices/file.c src/devices/datetime.c src/uxn11.c -o bin/uxn11 -lX11
If you wish to build the emulator without graphics mode:
gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/file.c src/devices/datetime.c src/uxncli.c -o bin/uxncli
The first parameter is the rom file, the subsequent arguments will be accessible to the rom, via the Console vector.
bin/uxnemu bin/polycat.rom arg1 arg2
