It works fine with just the primary SD card now (or a USB drive which I'm using). The core uses HDD images in .hdf format, as well as floppy images in .d88 format.

Hello,
With this latest version of the x68000 corel, a game like akumajou dracula no longer has the wallpaper at the intro or at certain points in the game.

No, it is set for intro, but when you enter the castle some elements of the scenery are missing

I have uploaded a new RTL.
The change is that 32bit transfer of DMAC is supported.

Finally took a video to demonstrate the issue issue I see with Geograph Seal:

It looks like everything 2D is fine, but anything 3D is corrupt.
This seems to happen with all X68000 core versions.

Thanks you Mr Puu for the new version today!
On the other hand, there are programs that have display issues that I didn't have with the previous version.
(ex: Mishell.x software)

Geography Seal game seems to be working better now

Viewpoint game still have the same display issues that looked like Geograph Seal
Akumajou Dracula also keeps display issues.

I've updated the RTL about three times in the last few days.
As for the contents of the correction, the DMA is corrected and the addresses related to graphics are reviewed.

Many thanks Mister Puu !

The latest improves Chase H.Q. a little bit, the game doesn't crash any more on the radio screen, speech and music are now played along with the scroll text. Unfortunately the game stops responding to the button press (worked earlier in the game) and it still hangs.

Love to see so the X68000 is coming to shape. Thanks so much mr Puu!

I don't know if testing is appreciated, but I tried Bubble Bobble and it loads fine but hangs up a few seconds into play.

Hello, Mr Puu do not know if you know that Jotego has a Clone YM2151 in verilog close to perfection and already ready and open source, if you could maybe put in your project :)

Great work so far Puu!
R-type is having layer transparency issues with the recent releases however. No playing required, as you can select "demo" levels from the menu.

Well I took the version of JT51 that Kunihiko made for his version of Mr Puu's x68k code to use on the DE0-CV and i was able to successfully make it work by changing the lines that Kunihiko says to change, in addition to adding the OPM_JT51 path on the VHD that he modified in his git.

If someone wants to test to see the difference, sound is as it should be in ym2151.

I hope not to be upset Mr Puu I just wanted to see if it really worked, I'm not developer xD

Here are the links to kunihiko's git:

https://github.com/kunichiko/FPGA-X68k-DE0CV

and the OPM used the JT51 that he modified

https://github.com/kunichiko/FPGA-X68k-DE0CV-OPM-JT51

The original git if you want to implement in your way in your project:

https://github.com/jotego/jt51

Thanks for the hard work in bringing the x68k to mister :)

Hi,

With every x68000 core that I have tried to start I get an out of sync video on my Sony BVM. I'm using the IO vga out here.
I have no issues with other cores. Do I have to change the mister.ini video settings for this specific core?

I tested this with Akumajou Dracula and I think it sounds much better, at least with that game.

As a side note, in the 2nd stage on the raft right before the skeleton boss, there is a graphical glitch on the top and bottom before the water starts rising.
The missing graphics in stage 1 are fixed in the latest build though.

edit: I attached a screenshot of the issue.
edit2: found another bug, stage 13 onward is missing graphics, upon transitioning to stage 13 from stage 12, the cog in the attached screenshot is missing, once you get to stage 14 or 15, all you can see is the candles. Upon reloading the save, you get the save selection menu graphics on top of the game graphics.
It also looks like there are minor graphics bugs in the HUD area at the top.

Hi, best way is Mr Puu implement in his design, I just put it the way it would work, but for him to see that it is better than the implementation he made of the sound chip, now is to wait if he will put the jotego on the x68k correctly

Hi, thank you for this experiment!
It looks like if internal core timings (write timing to the JT51 core) are in sync or well regulated, sound is produced VERY nicely.
Many games are still having this signal timing issues and experience incomplete sound output; however I tried with MMDSP and a dedicated MDX sound driver to play various X68000 tunes. Result is top notch and bug free, very clean and wonderful music playback is possible. :D

The DMA fix released on 8/27 revealed that there was something wrong with the writing on the SASI HDD.
I have uploaded a modified version, so please update it.
