Reply on your old posts about Alltynex and Mad Stalker.

With the added "-ram 6M" for fmtowns (works good with mame):

Alltynex is working now

Mad Stalker can be loaded now, but it freezes when you want to play
(Can you test your version again of Mad Stalker ?)

Pictures of Alltynex (works also in lr-mess, but has some slowdowns on start):

Pictures of Mad Stalker (it freezes on the second picture) :

@Folly Can you give me a quick reminder on how the hell to do this? How do I get ram - 6m working? Do I need to download your fork again?

@adambegood

You can update my script if you want.
Everything is described in the first part of the first post.
https://retropie.org.uk/forum/topic/29682/development-of-module-script-generator-for-lr-mess-and-mame-standalone/1
The fmtowns system with -ram 6M is install-able from the special systems with slotdevices.

Or if you have fmtowns already installed you can just add -ram 6M in the lines like this :
In /opt/retropie/configs/fmtowns/emulators.cfg

lr-mess-system-fmtowns_-ram_6M-cdrm = "/home/pi/RetroPie-Setup/scriptmodules/run_mess.sh /opt/retropie/emulators/retroarch/bin/retroarch /opt/retropie/libretrocores/lr-mess/mess_libretro.so /opt/retropie/configs/fmtowns/retroarch.cfg \fmtowns /home/pi/RetroPie/BIOS/mame -autoframeskip -ui_active -ram 6M -cdrm %ROM%"
mame-system-fmtowns_-ram_6M-cdrm = "/opt/retropie/emulators/mame/mame -v -c -ui_active fmtowns -ram 6M -cdrm %ROM%"
mame-system-fmtowns_-ram_6M-cdrm-autoframeskip = "/opt/retropie/emulators/mame/mame -v -c -autoframeskip -ui_active fmtowns -ram 6M -cdrm %ROM%"

Good luck.
Let me know if you get it working ;-)

AdamBeGood

@folly So if I already have fmtowns then I can just amend the emulators.cfg lines for this? I do have that installed, so that should be easy. I'll try that tomorrow!

Folly

@adambegood

Yes indeed, this would work.

But you should check the "front-end" script later on.
I works really amazing ;-)

AdamBeGood

@folly I am sure the script is great, and when I have the time I'll definitely look at it.

Allyntex is looking good on mess, Turbo Outrun runs much better on mame now - definitely playable.

I get Blank Screen with Mad Stalker - which emulator selection are you using for that?

Folly

@adambegood

I used mame for "Mad Stalker" but it freezes and therefor is not playable.

I was thinking maybe you have a better version.

I read that fmtowns hash tables are improved in mame 0.235 .
This should mean better game compatibility.
We should test this in the future.

AdamBeGood

@folly I'll give it a go again but my version wasn't even getting that far...

More compatibility is always good!

Bump. Finally got both Mad Stalker versions I have to fully boot, but encountering the freezing issue you mention. I hope to have some time to get back to exploring more of these retro games and systems, if work slows down enough over the holiday time...

@testudo

Great, I like to hear about your tests ;-)

Seconded! Good work.

@adambegood @testudo

Finally I got MAD STALKER working.
Tested with fmtmarty, but should work with fmtowns too.

In :
/opt/retropie/emulators/mame/hash/fmtowns_cd.xml
You can find that the mouse on port 2 has to be disabled with this game.

So you can use a game specific runcommand emulators.cfg line.
Then disable the mouse in the mame gui.
After that the game-specific config is written after quitting the game.
Next time it will use this config if the game is booted with the game-specific line again.
(It works with both mame and lr-mess)

AdamBeGood

@folly Great effort! I'll try this out when I get the chance. Brilliant detective work.

AdamBeGood

@adambegood I've had a go now but I get a black screen when the game shoud lanuch. I'm using mame fmtowns -6m

I'll have another try in a bit.

Folly

@adambegood

-6m is not needed with this game it works with the default (2m).
-6m is not bad though ;-) .

Make sure you load with game-specific, otherwise, when you edit the mouse setting, other games will have no mouse.

Good luck !

I use these files (running the .cue with fmtowns) :
pi@raspberrypi:~/RetroPie/roms/fmtmarty $ sha1sum M*

AdamBeGood

@folly Hmmmm I have a .chd, maybe the file is bad then. I'll look for your version.

Folly

@adambegood

Btw
You should use frameskipping,
It can take a while before the game starts.
It takes about 30 seconds, on my end.
With a CHD it can take longer because it's CHD is compressed.

You can check your mailbox.

I left it for ages...

I've actually found it myself but I'll check my mailbox. I have to go out now but I'll try the Folly version later! :)

Folly

@adambegood

I have to out too.
I hear it later.

Good luck !

I'm still seeing black screen, I presume I just run the .cue yep?

Should I update my MAME core?

Hope you're having a good day.

Folly

@adambegood

I had to work, thankfully no rain.

It's good to update mame.
The binary is equal or higher than 0237.

But I think it's something else.
Do other games run ?
Does lr-mess work ? (or is it the same story ?)

Check your runcommand.log.

Btw:
Autoframeskipping doesn't work that good over here.
With F9 you have to press until it's on frameskip 10 to get almost fullspeed.
