Cannot run SD Snatcher, MSX2 [SOLVED]

Zering

@mitu Yes. And then it hangs.

I know I've got the right system roms because openmsx is actually kind enough to let you know what roms you're missing, should you be missing anything.

It asked me for the following files :

fmpac.rom
phc-70fd_basickun.rom
yrw801.rom

Once I loaded all the roms in the appropriate directory, I was able to select this machine, and I even played some Metal Gear 2.
Now, whenever I try to switch to this machine, the emulator hangs.

Zering

Does anybody else have any ideas? Lr-bluemsx clearly seems like it should be able to emulate the SCC cartridge needed to run my version of SD Snatcher, but it still doesn't work.

Edit: I got the game to work! I had to use a pre patched rom. Still impossible to use the SCC but it's running fine on lr-bluemsx with PSG sound. Thanks @mitu for trying to help.

@Zering I'm going to try this today I think, I've wanted to play SD Snatcher for a while.

@Zering

I have it also working in lr-bluemsx.
(no SSC though)

Tried in core option(use F1), different "cartmappers" to get SCC working. No effect. You have to RESTART !
bluemsx_cartmapper = "Auto"
bluemsx_cartmapper = "scc"
bluemsx_cartmapper = "sccplus"
bluemsx_cartmapper = "snatcher"
bluemsx_cartmapper = "sdsnatcher"

Perhaps we have to see in the logs.

Zering

@Folly I have restarted several times with all those mappers. No effect whatsoever.

It appears there should be an option in the core to manually insert the sound cartridge that simply is not present.

Edit : the PSG soundtrack is pretty bland compared to the SCC by the way.

Indeed, I also had no effect !

Will look into it later on.

Zering

@Folly This is relevant.

It appears the function does exist in bluemsx but I would guess that it hasn't been implemented in the libretro core for RetroPie.

I get the MSX splash screen and then "Insert Sound Cartridge" also. Was the answer just using a different ROM or was there something else you did to get round that on lr-bluemsx? Thank you.

I am using a pre-patched Project Melancholia ROM.

@Zering @AdamBeGood

This should be relevant :
http://www.msxblue.com/manual/commandlineargs_c.htm
http://www.msxblue.com/manual/rommappers_c.htm

Perhaps we can add something in the commandline.
As alternative for the special cartridge menu.

Zering

@AdamBeGood There are three melancholia patches, two with SCC and one without.
The one without works just fine but the music is a real letdown.

I'm not sure how that would work, Folly, I'm not particularly skilled with that sort of thing.

On the other hand if either of you knew how to wade through the BASIC menu in lr-fmsx, I could try to see, in the meanwhile, if either version of the game works.

Folly

@Zering @AdamBeGood

SCC works in openMSX by adding Hardware/extensions/Konami RA-011 ......
Here we can test our disks, if they work with differen SCC options.

Zering

@Folly Does that extension work while using a c-bios?

Openmsx opens up a new problem though. Can we map joysticks in that emulator?

Edit : Openmsx still won't run .dsk on my end. I'm still trying to work it out.

Yes, I think so. But C-BIOS will not let you run DSK files.

Did that a very long time ago, I think it's possible.

I'm preffering lr-bluemsx if it works. But openMSX is better in a lot more things.
OpenMSX can be used for testing our disks. Here we can find out with which SCC they will work.

Zering

@Folly Yeah I only remembered that about C-Bios after I posted.

It also occurred to me that the issue with lr-fmsx might be the same. It only boots me to a BASIC prompt when I try to play a .dsk file, but they are few and far between so I never really noticed the issue before.

Edit : lr-fmsx would be my preference because of how easy it is to set up joystick controls.
However, at the end of the day, I'll go with whatever works.
I can't help with the testing of SCC as I can't get openmsx to work.
However if you guys want to try and sort this issue I'm very happy to help any other way that I am able.

The keyboard mapping in any lr cores should be easy if you use this trick so that shouldn't be a problem. Obviously doesn't solve the SCC issue though

Zering

@retropieuser555 I've tried following the instructions in this thread, with no luck. However I haven't tried using xboxdrv, how does that work?

I'm in the same boat as you now, Zering. Non-SCC copy of SD Snatcher works on bluemsx without any problems. Very annoying that they haven't included the SCC options in the libretro core.

.dsk and .m3u don't work on OpenMSX for me, although .roms do.

Zering

@AdamBeGood my understanding was that it is included, but that it doesn't work.

Yep, sorry, my mistake.

I am glad to be able to play the game, even if the music isn't what it could be. Thanks for starting the thread and giving me the kick I needed.

Zering

@AdamBeGood No worries at all. I'm playing through Soul Reaver, but once I'm done I'm starting SD Snatcher, fix or not. We could discuss the game as we go?

The MSX library seems chock full of gems like that. Six out kf eight disks of Illusion city for the turbo R have been translated and I hear that is also an incredible sci fi RPG.
