@RetroGamer02 Let me explain myself. It could be possible to make a FPS using this engine and the textures from Blasphemer? I don't mind losing fly, look up/down, pushing sectors, etc.

I think if it could be done it would be a job for DoomHack whom does the engine work. Even if I could make the changes needed I am focused on FreeDoom right now. Sorry to disappoint you. Most of my work is editing resources to work within the GBA's limits.

@RetroGamer02 You are doing a great work. I didn't mean to push you. If you do the tools, someone else can take them a do other things with them. :) (excuse my english)

WOW this is amazing!

 

Now I'm curious about the songs, since the audio engine is different from the Sappy one.

It uses Impulse Tracker music instead of midi so the music all had to be converted and use no more than 6 channels which causes some loss but cant be helped. Also thank you all for your kind words.

Oh yeah, I realize now that is actually a Source Port and not a Doom GBA Hackrom lol

New build with some optimization done to E1M1 and E1M6. Plus some small other edits.

I will sometimes just edit a post with a new build instead of spamming posts so check back every now and then. =)

Looks like Blasphemer requires a Hexen limit removing port

Blasphemer is the Heretic equivalent to FreeDoom. For HeXen supposedly it's Zauberer

Whoops guess I got Heretic and Hexen mixed up sorry.

Found out there is a crash that can happen in E1M7 around a switch will have to figure out why.

Well it does not seem to be the switch its self but something near it.

Gonna spend some time redoing stuff in E1M7.

New build redid E1M7 from scratch and removed some unneeded stuff from the rom.

Is there still interest in this project? I may consider working on it again.

Looks like doomhack has still been updating the engine that might help the speed a bit as well would have to see.

I am interested! You've done great work with this project, I'm excited to see the progress. I had been keeping an eye on the Github page, is the intention still to update it with the new updates?

I'm glad to see there is still interest in the project if you are keeping an eye on the github make sure you are looking at the MapOpt branch thats where the newest updates are. =)

Great, I'll check it out. Thanks!

New build https://mega.nz/file/vOJjyKpB#biQeyN2vUH9H-P94fAA3WskmhfIVsD0hibSHKDJalRA

E3M7 and E3M9 now work though there is a section in E3M7 that will need more work to run fast.

Next up to start work on Episode 4.

@RetroGamer02  Thanks. How much coffee do you drink?

@RetroGamer02 I don't know the tools or the process to make new Fredoom versions for GBA, but it seems to me you work fast.

Most of the work is optimizing and reducing the complexity of maps to work within 256kb of ram the GBA has. Also thank you. =)

I mainly use Ultimate Doom Builder and then Slade 3 to apply optimization such as sidedef packing.

[rainElemental]

@RetroGamer02 Cool to know. Also, try to not overheat yourself. :)

[RetroGamer02]

E4M2 and a few others may take a while the map is huge and I have been doing some other stuff the last few days will get back on it as soon as I can. A friend is also helping do testing in the meantime.

Saturn style transparency is now available used with permission from FastDoom's author as it was adapted from there.

Minor update only adds this modified feature.

Code is now also mirrored to https://notabug.org/RetroGamer02/GBAFreeDoom

 

Saturn style transparency doesn't really make sense here as a GameBoy has an LCD screen. There's no composite artifacts to blur it.

Goto Tools then settings in mGBA to set keyboard or controller buttons.

Edit: Oh and Hold the Run/Open button then press the L or R trigger button. Sorry sometimes I don't get much sleep.

Awesome port! Too bad, it does not appear to be able to run on my PSP's GBA emulator... :(

 

Would it be possible to bind weapon switch to another button, however? I find myself accidentally switching weapons when I tried to straferun.
