Current core is AFAIK only 10 MHz with 12 MB RAM (See screenshot in the area top left). Curiously memtest is giving me some errors. Will have to check that.

On a different topic, maybe some of you are interested.
Here is a small patch that enables MIDI over UART. This was easy because the core already has the MIDI interface implemented.
Support for MT32-pi could probably added easily, but I don't have one to test it.

I’ve been hoping for some updates to this core, oh and MT32-pi Support would be brilliant!

Posted: **Sat Mar 06, 2021 4:04 pm**

I have my MT32-pi ingredients ordered (now the long wait begins), so MT32-pi support would indeed be much appreciated!

Thanks @shira for the change on X68K core.
Testing with soundfont because I don't have my midi device yet.
This build use the source from last version with just the change of Shira thanks again !

Thanks for the work on adding MIDI over UART @shira and @wark91!

I initially had some wonky behavior but resetting via UART menu seemed to do the trick. Castlevania sounds great with an SC-88

Does anyone know how to set a core specific video_mode in the MiSTer.ini for this? I tried [x68000] and a few modes underneath but they didn't seem to take.

You're right :

does this build only do midi? no regular game audio right? it's either that or I messed something up

Posted: **Thu Mar 11, 2021 7:33 pm**

This build permits to add UART menu in settings of this core.
With this UART menu, you can connect a midi device (like MT-32, SC-55, ..) or use soundfonts.
When you launch a game compatible with those devices, you can select in game the audio you like.
For Akumajou Dracula (1993)(Konami), when you load the game you have a menu to choose the type of sound you want.

Thanks,

ok thanks I have a mt-32 but it wasn't plugged in so got no actual music , just some bleepy midi tones

Posted: **Thu Mar 11, 2021 8:35 pm**

If you don't use MT-32 device and want to have some kind of MT-32/SC-55 experience, you can use soundfonts like me.
Go to settings of the core -> System -> UART Mode and choose Midi.
In Midi, choose MidiLink -> Local, Type -> FSYNTH and the menu soundfonts will be available and you can select soundfonts you have already download and put on your SDcard in this directory : /media/fat/linux/soundfonts

Posted: **Thu Mar 11, 2021 10:50 pm**

I have an SC55 but seeing as there's no easy way to get the sound from it back into the Mister and out of the HDMI, I gave Fsynth a go. it works well but the soundfonts I tried are not as nice sounding as the real thing. is there an accurate Sound Font or a recommended one to use?

What are the games actually run perfectly on X68000 core please ?

Sorry if I'm dumb but I don't see a System menu. The options I see are:

Aspect Ratio
Reset
NMI
Power
FDD0
FDD1
SASI
SRAM
Sync FDD0
Sync FDD1
Eject FDD0
Eject FDD1
Load SRAM
Store SRAM

Posted: **Fri Mar 12, 2021 7:45 pm**

Go a page to the right, thats the system menu, there you should find it.

Posted: **Fri Mar 12, 2021 9:01 pm**

Oh my, yes I am dumb! Sorry. And thanks!

Does super hang on work on the core ?

Posted: **Sun Mar 14, 2021 9:53 am**

freeze for me after dos boot and echo off

Quick question, is the latest midi update of this core compatible with the MT32-Pi yet? I've got the midi audio working with uart & the internal Arm processor (and although it does sound nice the music trips up over itself) so gave the MT32-Pi a try but not getting anything from that.

If this core is compatible with the MT32-Pi, is there any chance someone could post a simple guide for MT32-Pi & X68000 usage? (I have successfully used the MT32-pi with the AO486 core so I'm probably missing something really obvious).

It doesn't seem to support the MT32pi yet. I was messing with it the other day and couldn't get any. I hope we get MT32pi integration soon.

Posted: **Wed Mar 17, 2021 8:16 am**

The support of MT32pi will required an update of sys and adding option in the core.

Am I right in that the disks need to be in .D88 format? I can only find .dim at the mo. Is there a way to convert?

Posted: **Sun Mar 28, 2021 9:45 am**

There are python scripts for all OS: viewtopic.php?p=19019#p19019
and there is the "Virtual Floppy Image Converter" from https://www.vector.co.jp/soft/win95/util/se151106.html (Windows)

I've been playing Akumajou Dracula on the X68000-JT51 core (date 20.09.13) and i've run into a bug with the core.

With start at stage 13/14, the GAME OVER screen gets superimposed over the gameplay area (see attached photos). This hides parts of the background tiles, but sprites seems unaffected.

This makes this level extremely hard

Another part (that I forgot to take photos of though) where there is a display bug, is in the 2nd level where the raft part starts. When you destroy the lionface, the screen turns partly blue with bugged out sprited, but as soon as the waterlevel has started to move, it disappears.

I wonder if another dev might be open to taking on the X68000 core and adding some video options. It would be great to see 15khz support and scandoublerfx enabled.

ok a complete x68000 noob here, I cant get it to run.

what i've done:-
update all script
downloaded latest ( i think ) beta 20.09.13

when i run the core its a black screen, I can press F12 and load d88 file or the sram and the hdf files but nothing happens just a black screen.
F11 does nothing.

any help please..

Hello,

Did you restart your MiSTer?
Running one Core behind another can be problematic.
Do you see the rom loading when the Core starts?

Posted: **Sun May 09, 2021 5:46 pm**

i see nothing but a black screen no matter what i pick
