So we get to play a non-bastardized port of doom on the go? Count me in.


Yep! That’s exactly what I set out to achieve!

I bought a Game Boy Micro from my friend. It had GBA Doom in it and when I told him he's like, "oh, you can have it"

 

I'd probably play this version a lot more.

 

edit: also, do you have an afterburner installed? That screen is way too visible.

Yes. It’s a modded GB with an IPS screen.

give a man a game, he'll game for a day 26 years, teach a man to program and give him the source code for said game and he'll make a port to a device with a fraction of the original required hardware specifications, and make it far superior to the official port

Well I gave a quick download and erm... I'm lost on what to do next. I saw it can convert IWADs to GBA so I kinda wanna do it with plutonia for the lols. :P


Build instructions are at the bottom of the page here: https://github.com/doomhack/GBADoom

I'm at a loss for compiling it too, both projects even. I installed devkitarm, type make... it complains about a missing gba_rules file (doesn't seem to exist anywhere), I remove the include line and then it's looking for a mmutil command that doesn't exist either. Bummer.

 

on GbaWadUtil, there's a GbaWadUtil.pro file that looks like a Makefile but doesn't contain any targets.

 

EDIT: OK, half of the problem were solved by using the official binary packages, the devkitarm package in AUR seems to be incomplete. That at least lets me run "make" on GBADoom until it complains about the missing IWAD header... and I still don't know how you're supposed to compile GbaWadUtil.

You are amazingly talented! I never thought I'd ever see full PC doom running this smoothly, at this point we've only seen a Jaguar based/Custom Engine port.

Thank you everyone for the lovely comments. I’m back from my vacation now so I’ll pick this up again soon and get some of the issues ironed out.

 

Sorry the build process is a ballache. Sadly, since the GBA only has 256kb of memory, I have to rework some of the data structures and the wad has to be embedded in the rom.

 

Big thanks to @Bloodshedderfor allowing me to include his Chiptune Remixes of the Doom music in this project.

 

Thanks for the videos @Kippykip.

I've seen it running recently, have plans to begin tinkering at runs in the port over the next month. Like I said on reddit, amazing job on this port!

Looking forward to seeing some runs! I’m interested to see how the times compare to the PC version or if there are new strategies that are found.

Well guys I just had a play around trying to get one of my favourite Doom levels running on doomhack's GBA port. 

Although it happens to be one of the biggest official Doom maps afaik, so I got Z_MALLOC memory errors for ages until I eventually got it going! (Albeit at a low framerate, I can probably make some further changes)

 

But here it is if you guys wanna have a peak!

 

I also remade this levels music, here's the Impulse Tracker file if you want to play around.

D_DM2INT.it.zip

I might remake all the TNT music in IT files eventually when I'm not working retail.

We'll have to see if there are more memory savings to make. I think there are still a few places we can shave a few kb here and there.

I suppose things like unused text wouldn't shave anything off memory wise, just rom size right?

No, all constant stings go in ROM so there is no saving there.

 

We're looking for stuff that is allocated with Z_Malloc() and friends.

 

If you build under Windows with Qt Creator the console Window will show a running count of how much memory is used.
