A decompilation of the built-in bootloader ROM of EverDrive-64 X-series cartridges. This is NOT a decompilation of the downloadable OS ROM.

Building

1. Install GMP, MPFR and Texinfo: apt install libgmp-dev libmpfr-dev texinfo
2. If you have not already, set MAKEFLAGS: export MAKEFLAGS=-j$(nproc)
3. Run tools/setup
4. Run make

Decompiling

Using decomp.me (recommended)

• Go to https://decomp.me/new
• Under Compiler, select GCC 4.4.0 (mips64-elf)
• Take the assembly starting with the label and ending right before the end directives, then remove all occurrences of " and \n. Paste this into the Target assembly field.
• Paste the contents of everdrive.h (without the #includes) in the Context field.
• After creating the scratch, under the Options tab, paste the following into the arguments field: -mtune=vr4300 -march=vr4300 -std=gnu99 -Wall -G0 -O2

Using ./diff

Run ./diff <start> <stop> [flags], where:

• start is the start RAM address of the function, minus 0x80000000.
• stop is the end RAM address of the function, minus 0x80000000.
• flags are additional flags passed to diff, such as -y
