Mednafen for GCW0
« on: September 26, 2015, 04:16:40 pm »
Here is a port of Mednafen for GCW0.

Last version: v1.5 (12/3/2016)

Installation
SET YOUR FTP CLIENT TO BINARY MODE OR ELSE YOU WILL HAVE TROUBLE
PLAYING GAMES !
AS FOR CD GAMES, CHECK YOUR CUE FILES AS EVERYTHING IS CASE-SENTITIVE !


The installation is pretty easy, put all (or some) OPKs in /media/data/apps.
Then put all your bioses in /media/home/.mednafen.

Atari Lynx requires lynxboot.img.
PC-Engine requires a syscard file for CD emulation, it needs to be called syscard3.pce.
PC-FX requires a bios file called pcfx.rom. (MD5 : 08e36edbea28a017f79f8d4f7ff9b6d7)

Everything else should work out-of-the-box.
When you have to run isos, use the cue file instead.

Controls
Exit : Select + X
Switch screen modes : Start + A
Configure Controls : Select + B

Hi,very nice thanks !!!!!

Few comments:
-So far, Lynx works but if press Start the emu crashes going back to dingux
-Cant make any PSX games work... Did everything according to the readme, but game select gives an 2 seconds black screen and goes back to dingux..


Gonna see how the PC engine goes and let you know

Regards

As complement:

PC Engine is a BLAST with the games I tried; Very nice
PC Engine CD is not working for the games I tried even after renaming syscard and putting in .mednafen folder

Thanks for testing !
Yes, PC-Engine CD games should work but i made a mistake :
the syscard file should be called syscard3.pce
Sorry for that

As for PSX emulation,
i think it does not play them because it does not detect them as PSX games.
I should release the PSX Core seperatly i think.
Note that you need the bioses for PSX.
They are (by default) called :
scph5502.bin for the European BIOS
scph5500.bin for the Japanese BIOS
scph5501.bin for the American BIOS

EDIT: Updated the config file for Lynx, it should fix the issue care16la20 had with the start button exitting.

WOW! Alright, I wish I still had my zero to test for you Gameblabla... I'm sure you will figure out all of the kinks, etc.

Thank you so much for this release!!!

Hi ,
renamed to syscard3.pce; But is still the same behavior with the PCEngine CD isos

So , at least for now PC engine and Lynx (this one in a very small window) are working perfect

Yes indeed : Using CD isos crashes the emulator, crap.
I think PSX is affected as well so it will probably not work. (for now)
I'm looking into this.

EDIT: NOO.
It's bad code produced by GCC and this time, it doesn't even work with -O 0, crap.
I will look at this further but this will probably be fixed only until the next toolchain comes out.
(spoiler: IT'S NEVER GOING TO HAPPEN)

Any luck with the PC-FX core? Yes, most people think it's worthless because of all the dating sims, but Der Langrisser FX is amazing

So i started from scratch without using my makefiles :
PC-Engine CD games are now working properly.

I have enabled all the other cores as well,
so you should be able to play PSX or NEC PC-FX games.

Keep in mind though that PSX and NEC PC-FX emulation will not work
fullspeed without frameskipping or (something i have yet to see happen) overclocking.

Any luck with the PC-FX core? Yes, most people think it's worthless because of all the dating sims, but Der Langrisser FX is amazing
Saw it but i never played it, i like the intro though.
I doubt it will play fullspeed without any frameskipping though...
You should try to enable it in the config file.

Can anyone confirm PSX works properly?? I have attempted to run certain game file images via QEMU but it is limited with regards to files that exceed 512mb... unfortunately, I cannot test/confirm PSX to work yet...

Anyone with a GCW ZERO... even if its low framerate, does this emu work? Any thoughts be appreciated...

Thanks!

Hi,

Now the PCEngine CD is working pretty nice as well ; Congrats !!! The only thing i noticed is the audio being a little choppy but the framerate seems to be 100%

PSX by the way is unplayable; Most of the isos I tried crashed, and the ones that open gives around 1 fps already during the bios animation sequence ...

Regards

I would agree... i tried CRASH BANDICOOT 2... the game won't load at all through QEMU. It just crashes and returns to the main menu of OpenDingux, unfortunately.

Mednafen got updated, i highly suggest you to upgrade.
Don't forget to update the config file with the one in the zip as well !

PSX didn't worked because Mednafen was not detecting most games as PSX games for some reason.
For this reason, i had to release it as a separate OPK file. ("MednafenPSX")
I personally was able to play a PSX homebrew game with it. (it was not too slow actually !)

I have improved the controls as well.
If you ever have an issue with controls,
you can update them by pressing Start+Select.

To Exit, you have to press Select+L now.

Hope you will enjoy this new release !
