MiSTer FPGA Forum

I am pretty sure that most of the sounds you are hearing from the MiSTer are still samples. The walking sound is not a sample anymore. We just need to get the rest of the sounds converted and it will be a lot better. Also, you need to use filters in the core menu. This is by design, although I am not sure I agree with it because how is anyone supp...

Could someone please post a known working MRA for this core? Thank you. I'm not sure what the issue is as the current MRAs should work. You could try editing Donkey Kong (US, Set 1).mra or making a copy and editing the line <rbf>donkeykong</rbf> replacing donkeykong with the full name of your rbf that you placed in cores/ to make sure it's using t...

The second rbf file released yesterday (May 1) sounds a bit better to me. If I had to try and articulate what still sounds different to me, I’d say it has something to do with the attack and the pitch. I think the original perhaps has a sharper attack and more low end. This still sounds a bit “squeaky” to me. There is also a periodic increasing pit...

I commented on the original PR that got merged. I'm in the camp that was slightly bothered by the samples in that they can't reproduce the random nature of how the walking sound is actually produced. I'd think though that anyone sensitive enough to want an improvement in the existing walking sound would not be convinced that this is an improvement....

That's a good point and I'm not absolutely sure it's correct. About the most I can say is that MAME sounds right to my ears but that's subjective of course. Looks like the MAME 54xx simulation code came along later and originally they used samples. At least their 54xx sounds pretty close to the samples. The MiSTer cores still don't sound quite as g...

Xevious is worse with a speed of 750kHz. 250kHz gives me the same speed explosion as MAME. PR for Xevious is here if you want to take a look.

Yeah, I actually got motivated enough this morning to try and finally get a dev environment on my Mac so I could play around. I ended up with a Docker solution that works. I decided to see what would happen if I simply cut the speed in half by making cs54xx_ena_div four bits. With that it still sadly had less low end than MAME but I could tell it p...

Thanks for looking macro. I see that now as cs54xx_ena_div is three bits and is incremented once each time through the six slots. This must work differently than it does in MAME as the 54xx runs at 1/2 the CPU speed there and sounds correct. I'd expect it to be slow on the MiSTer at 1/8 CPU and not fast.

Looks like the explosions are generated with the 54xx. Researching a bit it looks like the CPUs are supposed to run at 3072000Hz and the 54xx at half that. Perhaps the 54xx is running at the CPUs speed instead making the explosions fast? That would sound about right at least.

I've noticed that in Xevious both the player and bomb explosions seem to play at too high a speed. In Galaga there appears to be a similar issue with the player explosion. In MAME with the same ROMs they seem ok.

Thanks for the reply. I don't notice an issue with the functioning of the X-Arcade, just the mouse. I'm using the X-Arcade in keyboard mode so it attaches as a USB keyboard. With the powered 4 port USB hub attached and the mouse attached to it (I've added the device descriptions to the output): # lsusb Bus 003 Device 001: ID 1d6b:0003 (USB/IP Virtu...

So, this appears to be an issue with plugging the mouse into my USB hub board. If I plug the mouse into a separate powered USB hub and plug the hub into the hub board it works fine. If I pull power to the hub it stops working. At this point I was pretty sure it was a power issue. I'm using the standard DE-10 2A standard power supply. When I replace...

I have a main USB keyboard and two different joystick -> USB keyboard devices (a 2600 daptor-II and an X-Arcade). When I have either or both of the joystick -> USB keyboard devices connected, I can't use the USB mouse. Disconnecting them makes the mouse work again. I've tried removing the .cfg files for the devices with the same result. It appears ...

I have an old X-Arcade that I recently upgraded with the USB board and it works well with the MiSTer in its default configuration (as a keyboard). One thing I like about it is you can configure each stick as four way or eight way. I keep one a four way for Arcade games like Pac-Man and Donkey Kong.

I just got a 2600-daptor II 9 pin to USB joystick adaptor and am struggling to get it to work within any cores. It does control the MiSTer menu so it appears to be recognized and somewhat configured. I've tried in each core to configure it but I so far I've had no luck controlling any games with it. In the logs it's listed as: "USB HID v1.11 J...
