I am also having sound issues with Chourensha. It seems, both non JT51 and Jt51 versions have different issues with generating all instruments consistently, as well as the noise channel.it would be soooo awesome, if someone could look into it. It's my favorite game! :)

Is the second SD still needed with the beta updates?

nope. just put the X68000.rom in the /bootrom directory, and your disk images in /X68000.

Hi !

How amazing this x68k core is getting ! Thanks for the hard work !

I have tried the os9 images from this site : https://nfggames.com/X68000/index.php/O ... /?upload=1

Unfortunately the "bootloader" does not seem to find any OS-9 kernel. Getting into that bootloader seems to indicate the image itself is somehow readable I suspect ?

Using the XM6 Pro-68k emulator I get this screen :
XM6 booting os9

and os9 boots into its gui

With MiSTerFPGA :

I did try inserting the $00005194 address in MiSTer but I get strange keyboard input and it does not work any better. Same behaviour with X68000_20200715.rbf & X68000_20200913.rbf. As you can see on the screenshot, the first text column also has disappeared starting with 5th line.

Thanks helping !

The latest blog post from 12/12/2020 has an attachment "release-F68k_DE0CVDEMU.201212.qar" that does not contain an rbf file for MiSTer. Could somebody please upload the latest build for MiSTer?

プーさん、ありがとうございます‼ I'm very happy to have a device I can play these old PC games on.

Just to report on my testing with some RPG disk images I happen to have on hand:
  • Lagoon is crashing on boot for me. On emulator, it starts with a line drawing of the ZOOM mascot, as seen in the screenshot below. On the MiSTer, it freezes with just the yellow cursor in the corner and making a buzzing noise.
  • Arcus Pro 68k loads and runs. Music and text play during the intro, but no images are rendered. It's trying to draw something, since there's a slightly darker black square where the image should be in the attached screenshot from the MiSTer.
  • All four Dragon Knight games work fine.
Once again, thank you for your work, and I look forward to trying more titles on this platform in the future!

Could you tell me what changes you made?
I tried to to change it with this one (https://github.com/kunichiko/FPGA-X68k-DE0CV-OPM-JT51), which basically works.
But I'm getting some clicks and pops in the wrong places, so I might have missed something.
In your version the sound looks clean.

Thank you.

For anybody interested I modified vertical refresh to be 55.3 Hz which is closer to 55.45 Hz which is what most games use. For some reason sound is Nemesis 90 Kai is not perfect I believe neither with JT51 or the default implementation. I wonder why this could be. I want to try to force the core to think it's a 16 Mhz and 4 Mbyte machine, which I believe requires creating a special sram.dat file.

Any idea how to fix sound? (I included the lastest JT51 implementation from github but in Nemesis 90 there are missing sounds, e.g. powerups do not sound).

Does x68000 core support 16 Mhz 68000 and 4 Mbyte RAM?

OK. I respond myself. I recompied X68000 core w/ sysclock set to 16 Mhz. Now Nemesis 90 Kai loads pcm4 (it loaded pcm1 before), but sound still not good (missing sounds).

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

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 8-)

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.

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,

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

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?

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

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.

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