Porting OpenEmu

[grelbfarlk]

Thanks for that the SDL folder build just fine, but MorphOS and my A4000 lock up when trying to compile the Musashi core. Pretty strange it's on both. Haven't tried GCC 4.4.5 yet.

[emufan]

hmm, not sure , but here again a support tool does generate different files.

cc  -o m68kmake ../musa/m68kmake.c
...
./m68kmake . ../musa/m68k_in.c
...

change to musa folder and check if the 'm68kmake' tool is build properly.

zoned: dgen-68k-WIP.lha

sound is now working, using libSDL 1.2.15
just have to fix the default config path. default false colors too.

use this command line to start dgen:
dgen -r dgen.cfg rom.rom

- if you get false colors use F5 until colors are correct.

- F6 will do some scale effect

(included readme says F4 and F5, is a mistake)

#1) just report back, what FPS you get.
in winuae with JIT i get 30-45 FPS, depends on the game. but very playable

#2) i could fix the default config path - not yet released.
in system.h

#ifndef __MINGW32__
//#define DGEN_BASEDIR ".dgen"
#define DGEN_BASEDIR "PROGDIR:"

this does work, and dgen will read dgenrc (configfile) in current directory

#3) default false colors "fixed" using dgenrc setting:

#  swab      - Swap video output endianness.
ctv_craptv_startup = swab

uploaded to aminet

I was able to build BlueMSXlite. it does show a black screen only.
when loading a config / system roms, it does crash with a system alert #80000004.
build again with gcc 3.4.0. had to add strcasestr and strncasecmp from old glibc.
additionally I had to disable a soundchip, some weird gcc error.

maybe I can make it work.


#1) did anyone test dgen on a real machine, maybe vampire or 68050?

[xboxown]

BWAHAHAHAH dgen!! DGEN!! BWAHAHAH

Are you really working on blueMSX??!! Please if you can port that..it would be superb! Meaning my Amiga will have the latest up to date MSX...KICKS AMIMSX on the butt and truly not needing AGA is superb! Not switching channels and working directly from RTG mode...woohoo!!

yep. it does work very well. if you have time, just report what FPS you get, with what game

Are you really working on blueMSX??!!

yes. but it's blueMSXlite - without gui, has some command line options.
it build without much trouble, but still refuses to work, if I try to load a config/rom.
maybe I can fix it.

[xboxown]

Can a person write a GUI in their favorite programming language??! Yes! YES! We can! YES! It is not a movie player..all it needs is a little window that with GUI a person clicks the game ROM, location of the bios ROM for MSX and click play button where it puts the parameter such as this:

BlueMSXLite #stringName where #stringName = DH1:ROMS\kingsvalley.ROM and inside the code it will be like this:

BlueMSXLite DH1:ROMS\Kingsvalley.ROM

and it runs the game with press ESC key it quits the emulator and returns back to GUI!

AAAAH! Quick! When you are done and successful in porting this, please, please, please please tell me all the configuration parameter for blueMSX so I can make a full functioning GUI for it!!

@emufan: I would test DGEN but main binary is missing from the zoned archive.
Just curious, could you by chance compile FrodoV4.1b from the sources FrodoV4_1b.Src.tar.gz so that it does not use FPU? Just for Vamp users like me

maybe not a full GUI, but we can try to insert some file requester which loads a config.ini for the many "Machines" emulated.

OMG. it was not there indeed, sorry.
now updated version in the zone: dgen-68k-WIP.lha

I will try later

[Marlon_]

emufan, do you by any chance know how to use git? I've started this Github organization called AmigaPorts (https://github.com/amigaports). And since you've been busy porting a bunch of stuff, I think it would be nice to put all the sources there, so people have an easier time finding the sources and can help contribute to making these ports even better.

this is a good project, but for now I put my stuff on aminet and include src code,
if I made some significant changes to the src code.
it's too much hassle atm, so I prefer to spend my time to build something.
but i'll keep it in mind

#1) Frodo is a pain, no clean build with either gcc 2.95, 3.0 or 6.x ....

devices/timer.h:
struct timeval {
    ULONG tv_secs;
    ULONG tv_micro;

[or]

sys/time.h
struct timeval {
	long	tv_sec;		/* seconds */
	long	tv_usec;	/* and microseconds */

both result in this:

Frodo/C64.h:
	struct timeval start_time;

error: C64.h field `start_time' has incomplete type

it does create a new struct start_time , based on timeval !?
so what is incomplete here?

#2) hmm, I can fix it, if i make a pointer from that field:

Frodo/C64.h:
	struct timeval *start_time;

dunno if something will explode, but it's taken by the compiler.
still a long way to a final build ...

You did it again! The dgen archive still uploaded without binary!! AhAHAHAH

nonono, this time it is there, look:

dgen-68k-WIP.lha:

2557644 Dec 10  1980 dgen  <---- the emulator
  12731 Dec 10  1980 dgen.cfg
   8392 Dec 10  1980 dgen_tobin
  12733 Dec 10  1980 dgenrc
      0 Dec 12 19:05 ram
    200 Dec 12  1980 readme-WIP.txt
      0 Dec 12 19:05 roms
  12731 Jul 26  1980 sample.dgenrc

only one generic buildd for 68020 -> 68040

	uint8 intr[4];		// Interrupt state
	bool instruction_complete;
	bool idle;

	uint8 via1_pra;		// VIA 1
...
	uint8 via2_ier;
};

does it matter?

[amigoun]

Now it looks like I have to find a recent ixemul.lib (no FPU) that works on vampire.

It's all about different standards.

ixemul.library 48.3 - has non-fpu version included. maybe ixemul.library 63.1 is generic, but not sure.

sooo many obstacles :/

[amigoun]

ixemul 48.3 soft float version giving me EMT trap error. Fpu version on WinUAE works.

one version must work with the Vampire, since xboxown reported so.
did you test ixemul-000.library from 48.3 archive?
maybe ixemul.library 48.0

[amigoun]

All the soft-floats giving me EMT trap error.
I had no choice but to use the soft-fpu femu then I got it working. But very slow - about 1 FPS or even less , more likely half the frame.
