WarpOS version of SDL

[Hedeon]

Took a few months... but the WarpOS SDL library has matured quite a bit.

See for some examples: [ Show youtube player ]

My attempt at C coding (well, actually copy/pasting other people's work) can be found at:

A bit late, but the answer is no.


Elf2Exe2 also adds a 68K hunk responsible for opening the powerpc.library and jumping to the PPC code (RunPPC) amongst other stuff.

Yeah, I figured as much. Too bad the source is far gone. It would be real nice to cross compile WarpOS stuff from linux x86-64.

How hard could it be....



Though lately as I try compiling larger and larger projects on the Mac Mini, I start to wish I could cross compile, though testing is a bit of a pain in that case. ScummVM for instance takes about 3 hours on the Mac Mini and that's with an SSD. FBA or MAME is like start before bed and hope it didn't stop sometime in the night.

Well, it certainly would be nice for me, as I try my ports on all systems.

Currently I have a setup where I can easily switch between compiling for AmigaOS 3.x, AmigaOS 4.x, MorphOS and AROS-ABIv1. I would like to make that more complete.

My only MorphOS machine I could use for compiling is an old Powermac G4 Sawtooth 450MHz, which would be painfully slow to compile stuff on.

I would very much like to get into the whole WarpOS Sonnet thing, but it's quite a steep expense curve to try and get hold of an A3000/4000 + Mediator + Sonnet/Rapture.

I could of course try stuff in UAE, but it doesn't always work like it does IRL.

A Mac Mini PPC isn't really that expensive but it's a silly expensive hobby anyway, then you need a MorphOS license too-then it's not really that cheap.



My offer still stands for a free* Rapture if someone wants to do some porting**, but that doesn't help much if you don't have an A3000/4000 or a Mediator.



Would be really easier to tempt the curious if the bar to entry wasn't so high.

I wouldn't recommend compiling on the rapture with a real Amiga. It's still 2.95.3.

That's not what I mean though.

You know the other option, and it's not really ideal but not totally crazy is you could do like Emufan did. Use your cross compiler and dump the elf on the Sonnet equipped Amiga and run Elf2exe2 there or UAE. Of course UAE takes a few tries to run it before it doesn't throw an exception. Doesn't that sound super fun?

[Hedeon]

I've looked into elf2exe2 and identified which part is added to WarpOS hunk files. When I have the time I will look into it further. I don't know if the programs you pointed to make ELF RELOC files which are different to the ELF EXE files from for example OS4. Also not sure if it really matters, maybe it handles both.

On a side note, I added a WarpOS SDL port of Ur-Quan Masters to Aminet.

Long story short, seems I'm having new bugs with the vintage version of WarpSNES on the new PPC board. The screen is not updating properly like the frameskip is now skipping way more than it is supposed to. Vintage WarpSNES runs nearly perfectly with sound on Sonnet, Rapture G4 and so on, just with the new Ragnarok board am I having problems.



So trying again to get Snex9x 1.53 rebuilt, attached is the work in progress. Seems to run fine on Ragnarok. Still missing Joystick support but it basically works for testing.
Old version crashed on non Altivec-equipped CPUs. Probably requires a very fast PPC, like >800MHz.

@grelbfarlk: I know I'm not allowed to mention f***craft but how about conversions of Stargus/Stratagus, Wolfenstein and/or Alien v Predator?

Stratagus has been working for a long time and BOS Wars "works" fine. I'll send it to you if you want. It's the tools to convert the assets to the engine that don't work right. So if the assets are available and work with the engine, the game should work.



So while Stratagus works with BOS, the Stargus tool doesn't convert the Starcraft assets into the right format for it to work.



Wolfenstein 3d? Or you mean RTCW?



AVP I played around with, it needs some Cowcat magic to make sense of OpenGL->W3D stuff. I thought it would be simple with SDL-GL but it seems to want to use gl/gl.h directly. Though a lot of it seemed to compile ok.


Looping back around to the beginning, I looked at FPSE 10.6 again, and it seems like the main executable is a tiny little 68k program which loads the plugins which do all the stuff. The plugin source is available, so maybe just maybe the plugins which handle W3D, Sound, etc could be compiled for WarpOS. Big and many maybes here. Or if anyone else would like to look at it and say "You're stupid and wrong and I don't like you" that would be a big help and I'd stop knifing around with it.

The rather large FPSE.DLL that I overlooked in the 68k archive I think has the main part of the emulator which doesn't appear to be in the source. So not reasonable idea.

Got this AmigaDOS alert on OS4:
