Re: MIST C64 core

The C64 DTV is a very neat piece of hardware that is highly moddable, but I think MiST core (and TC64) is more faithful.

Re: ZX-UNO Spectrum FPGA

I love that enthusiasm!

Took me a second to realize this recreated speccy is actually a Bluetooth keyboard... how do you connect it to the MiST? USB?

It is a much much nicer solution than my wireless keyboard with stickers from the ZX-UNO guys. :P

Re: Sprite limit in NES core

This also fixes flickering on some games such as the life bar in TMNT 1. Worth doing, albeit a very specific change so not sure how much work it would be.

Re: custom USB controller adapters

I can get directions working but not the buttons. I followed the example to the letter and tested for connectivity on relevant pins, I even tried using shorter connections but none of the button work. Maybe a problem with my board? Unfortunately I only have one right now :(

Re: custom USB controller adapters

i've though converter on arduino micro is what you wanted originally. And it only needs connector soldering. What's wrong with that? I'm currently exploring the Arduino micro, yes.

Re: custom USB controller adapters

I found this... it's similar to what I have i mind, but not entirely DIY friendly as it needs SMD soldering.
Also some of the souce code was hosted in personal pages which have been taken down (hooray for Github)
Still, here it is for reference: http://denki.world3.net/retro_v2.html

MiSTer on PVM

So I finally was able to test my MiSTer with a real PVM. I used a VGA to BNC cable, and edited /config/MISTer.INI to disable scandoubler and provide composite sync on the VGA HSync pin. Happy to say that most cores work really well. For some reason I couldn't get the Spectrum, Apple II, Mac and Moon...

Re: Mist expansion (in theory)

What puzzles me is how did we get so many cores for the MIST/MISTer? Where have all the developers go? And how many of those cores are still actively developed? Many cores were ports from older Terasic boards (e.g. DE1, DE2), or the FPGA Arcade Replay, oten with improvements along the way. Much les...

Re: Testing: Support for more HDMI resolutions and other changes.

The thing is, as Sorgelig pointed out, it is using a more generic upscaler which (for good reasons) doesn't give you that kind of control. In most use cases you just want the image to fit the screen. I noticed that it also adapts when you add a black border as in the NES core, which actually is nice.

Re: Testing: Support for more HDMI resolutions and other changes.

I never expected it to be trivial :D Just looking at the prices of the XRGB and OSSC show that good quality upscaling is very difficult. In theory 720p is an ideal ratio for 15khz because 240px3=720p. I wonder if I will get better results if I disable the scandoubler option, because maybe its upscal...

Re: Testing: Support for more HDMI resolutions and other changes.

Somewhat related, would it be possible to have an option on the upscaler about how to stretch the image? I'd like to try forcing it to only 1x, 2x, 3x, 4x as a way to avoid filtering. Basically it will have black borders but should give a sharper image.

Re: Question about Apple II core: GS compatible?

The Apple II core is not for the Apple II GS. It supports an Apple II+ with 128K memory and a Mockingboard soundcard (equivalent to an original IIe with the same soundcard) and yes it only supports .nib files. There is a small utility in the repository to convert .dsk to .nib. What's missing to be a...

Re: custom USB controller adapters

After googling around I think it's a bad idea to put a DC jack without adding a voltage regulator circuit or it might damage controllers. I guess I can just change it to holes to solder a battery holder on the back of the PCB.
