Hello Mr. Puu
What would be missing now is to be able to save the configuration of the x68000 core ... for example, the joystick must be configured each time the core is restarted

I'd love to change the subject of this thread to just be X68000 beta... Any idea how I can make that happen?

I've been testing this, some games appear squashed up or to the right, probably due to different resolutions. Very impressed with the core (and the original computer)

For some reason I need to set the "VGA to scaler" output to 1 on this core (vga_scaler=1). The games run, but the view area is very small.
On other cores this setting is 0 on my Sony BVM MiSTer IO setup (VGA to Scart > SCART breakout to BNC).

I thought that the X68000 core could also display in 15khz (at least for some games that support this) ?

The core doesn't support this at the moment. See a previous post from puu in this thread. It always outputs 800x600@60hz I think.
This is apparently due to the original platform he developed it on not having a scaler, so the core does some internal conversion itself.

Unfortunately this means most of the video timings aren't accurate, which may or may not be a big deal depending on the game in question and how far off of 60hz is was originally intended to run.

I found a sound issue with the last version with the integration of JT51. It is maybe a jt51 issue or integration issue. This issue is not present in on the core without JT51.
In the game Gradius 2, if you let attract mode play. At the game over screen a weird sound appeared until the Konami logo.
Can someone confirm it ?

@puu, for information there is some updates on TG68K cpu (https://github.com/TobiFlex/TG68K.C) It maybe helps this core.
This code is used on Amiga core.

Thanks,

It doesn't matter if you don't have the SRAM file. There is no problem with normal operation with the initial value. If you want to create it, create an empty 16kB file, put it in the SD card, select it as an SRAM file, and then select STORE SRAM to update the contents. Just selecting a file does not load it. LOAD SRAM is required to load.

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! :)

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
XM6 booting os9
0002.jpg (12.77 KiB) Viewed 13448 times
and os9 boots into its gui

With MiSTerFPGA :
mister-os9.jpg

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).
