Cannot run SD Snatcher, MSX2 [SOLVED]

@Folly Then that's probably it. Which files should I have in .openmsx/share/machines?

My directory is empty.

Mine are empty too.

Zering · 29 Oct 2020, 22:01

@Folly Okay, I think I'm on to something then. My nms and FMPAC.ROM are wrong compared to the last sha1 you posted, which are different for some reason. I'll try different files and update.

Folly · 29 Oct 2020, 22:04

@Zering

Try to search in /home/pi/RetroPie/BIOS/*
Perhaps you already have them.

fmpac.rom with sha1 9d789166e3caf28e4742fe933d962e99618c633d
should also work, according to the /opt/retropie/emulators/openmsx/share/machines/Boosted_MSX2_EN.xml

Zering · 29 Oct 2020, 22:19

@Folly IT WORKS! :D

The Sha1 didn't have to match for FMPAC.ROM and nms8250_disk.rom.
The last Sha1 values you posted have allowed me to get into openmsx, choose the Boosted MSX2, set it as default (this is very important). Then I could boot my .dsk files for SD Snatcher from ES. I put in the Konami extension for SD Snatcher. I'll have to compare with my non-SCC version to be sure but I think it sounds right.

@Folly, you are a legend.

Folly · 29 Oct 2020, 22:21

@Zering

Enjoy :)

Zering · 29 Oct 2020, 22:21

@Folly Haha well now I have to figure out how to map the controls, how to swap disks with openmsx, how to save onto the user disk... But the biggest hurdle is past! ^^

Edit : The SCC music is excellent, it's really impressive how much those old school japanese composers managed to squeeze out of 8-bit hardware.

Good luck, most things you can find in the menu.

Music is indeed super.

@Folly Thank you again for all your help.

Hopefully this thread helps @AdamBeGood too.

Okay, I'll have to do this in the morning or my wife will leave me.

So if I get into OpenMSX by booting up a .ROM game, then I should be able to change the machine type and then load Snatcher. That's my understanding... Well done for getting this sorted, both!

"I put in the Konami extension for SD Snatcher" - is it going to be obvious to me what that means?

Zering · 29 Oct 2020, 23:34

@AdamBeGood Yes - it's under hardware, then extensions. There are a few Konami SCC, one is exclusively for SD Snatcher and is well indicated. You'll know it when you see it and if you don't I can help you with it - in the morning. Don't want to be responsible for your wife leaving you ^^

You'll need to make sure that you have the five files indicated by Folly as well.

I have all the files with the correct checksums, I managed to get that done last night. I'll report back!

Thanks for the support. :)

Zering · 30 Oct 2020, 08:52

@AdamBeGood No problem. Let me know how you get on. I think you'll find the SCC music to have been worth the effort.

It works! For some reason my mouse stopped working almost immediately on OpenMSX but once I got into the menu via the console, it was okay!

I did a quick comparison against my non-SCC version, it is much better! Thanks to you and @Folly - now we should probably play the thing!

Edit - can I save the Konami Extension to happen by default or do I need to set it each time?

Zering · 30 Oct 2020, 09:03

@AdamBeGood I don't think you need to set it each time.

Saving and swapping discs is easy, now the only thing that needs figuring out is how to map F1, F2 and F3 to a joystick.

It's great you could get it to work! Isn't that music awesome?

Why F1 - F3? Are they the swapping buttons? I've had to work now so can't fiddle.. I don't massively mind having a keyboard plugged in anyway, I always play at my desk.

If I close and then reopen OpenMSX, I have to reload the Extension. It is not there by default.

The music is great!

Zering · 30 Oct 2020, 09:48

@AdamBeGood F1 - F3 are for pausing, saving and loading.

Mind you since you need a mouse and keyboard around to swap to the save disk anyway, it might be a waste of time.

Yeah, maybe a battle that doesn't need fighting!

Which leads me to wonder - how did people play those games back then? They seem to have joystick support yet joysticks in the early MSX era had very few buttons, certainly not enough to play a game with many possible inputs like Metal Gear.

Did people use the joystick for most of the gameplay, then reverted to the keyboard for more specific functions?

If anybody knows a bit about how actual MSX computers handled gaming, I'm all ears.

I think that would be the case, yep. I was just looking at the text for the Metal Gear manual.

F4 is "Transceiver", but then the core buttons are given as keyboard and joystick commands. So I think either just Keyboard, or Keyboard and Joystick would be the way.

The joystick would have always been connected to the Keyboard, so it wouldn't have been too much of an inconvenience to use both.
