I've made a few titles in all their glorious BGM that work under NEO4GDEMU.

Metal Slug for NEO4GDEMU.7z (517.8MB)

Metal Slug 2 for NEO4GDEMU.7z (378.3MB)

King of Fighters '98 for NEO4GDEMU.7z (512.2MB)

Last Hope for NEO4GDEMU.7z (160.4MB)

Neo Turf Masters for NEO4GDEMU.7z (280.6MB)

Bust-a-Move for NEO4GDEMU.7z (1.3MB)
https://mega.nz/file/NVh1HYpA#Mogen5Xpz ... 2PVUQmWVXk

If you have made any titles that work, let me know.

Summary:
-Working Titles:
Metal Slug
Metal Slug 2
King of Fighters '98
Last Hope
Neo Turf Masters
Bust-a-Move

-NON-Working Titles:
2020 Super Baseball
Aero Fighters 3
Art of Fighting
Baseball Stars 2
Bang Bang Busters
Fatal Fury - The Battle of Fury
King of Fighters '94
League Bowling
Super Sidekicks
Viewpoint

I've yet to see a working title that has "MACTOPIX" in the .IMG file. MACTOPIX is the pre-mastering software. "NON-Working" means it does not show up when 'Select Game' is clicked from NEO4GDEMU.

Great! I miss them for my collection, now I only miss the Art of Fighting titles. I also miss Fatal Fury 1 and Fatal Fury 2, I would like to make them myself but I have some difficulties.

Only certain titles are working. I PM'd megavolt85 yesterday, hopefully he has time to take a look at the code.

I'll look and see if any AOF or FF titles can be converted.

I'll leave it here in case someone wants to make a native application for windows

What I found out:

1. With IMG_insert.exe, there should be no spaces in either filename. Megavolt85 just posted the source code. There could be an issue with Windows 10 when running this program. A recent update to Windows 10 broke BootDreams.

2. Name of title not showing up after selecting 'Select Game' issue.
If "MACTOPIX" is in the .IMG then this happens. MACTOPIX is the pre-mastering software. Not sure why and I have no solution. Maybe there is something weird about the file system on the CD.
