Old invader game

[Steffan-68]

Alright folks. Here it is, with complete FM/OPL3 emulation. I used the Nuked OPL3 emulator from nukeykt/Nuked-OPL3: Highly accurate Yamaha OPL3 (YMF262, CT1747) emulator (github.com)
I also found and fixed quite a few bugs and typos in the original code. There may be more. If I find more, I'll fix and update those on my GitHub: https://github.com/a740g/QB64-Museum/tre...B-Invaders
Cheers!

Hey great job.
I couldn't have done that, thanks.
It sounds different to me than the original, but it's good.
The original was running in the DOSBOX and I tried to record the sound as best as I could and it sounds somehow different.
I had attached the sound further up in the 7zip file.

There is still an error, the top right is still missing the display of how much life you still have. Don't know how I fixed it at the moment.
And the pallet rolling is also missing. I had fixed that, but probably exaggerated a bit.

I'll take a closer look at your changes and hopefully learn something from them.
Now I'm going to sleep first, I have to work again tomorrow.
