This page is still very much a work in progress.
Last Updated 2023/03/20:
The last update was almost 6 years ago! Most of my time since 2017 has been
spent on things unrelated to Neo-Geo, but around December 2022, I decided to
return again.
Not only that, I come bearing a gift: NGPalTool, a tool for working with
Neo-Geo palettes. It's available on the Utils page, as well as below.
I am also working on a Fix layer tilemap editor, though I have no idea when
that will be finished.
Utilities
Stuff I wrote, or had a hand in developing. You should also check out the
general utilities page for more tools.
Tool Binaries
vasm
These binaries are hilariously out of date. Use at your own risk.
vasm is a portable and retargetable assembler. Ideally, you should
compile it yourself,
but I recognize that's not always possible for everyone. v1.7h is the current "release"
version as of 2017/02/06.
Older Versions/68000 with Motorola Syntax
Older Versions/Z80 with oldstyle Syntax
vlink
These binaries are hilariously out of date. Use at your own risk.
vlink is a portable linker.
Much like vasm, you are expected to compile the binaries yourself... v0.15d is the
current release version as of 2017/02/06.
Older Versions
byteswap (Hans Vahlenkamp)
Before I ported ROMWak, I searched the Internet for some open source tools,
including a byte swapping utility. I found one that fit the bill and am
providing it here, just in case.
Future Plans
No promises on release dates for any of these.
- Neo-Geo CD System Utility
- Anyone who knows how the Neo-Geo CDZ BIOS/system ROM actually goes about
booting a game should contact me so I can throw a bunch of questions at you.
- freem's Palette Tester — Example Neo-Geo assembly program that allows experimenting with the palette. Mostly done; need to work out a few kinks.
- Some sort of guide to programming the Neo-Geo, a la the "Nerdy Nights" tutorials for NES. Will likely involve using the freemlib. Very rough WIP, out of date!
- Various other utilities (both my own and other people's).
- More examples for the freemlib.
- Actual games (this will take a while).
