Re: MiSTer PCXT

I believe the UART flow control needs to be enabled in the Cyclone-V SOC configuration inside of the HPS. I recall reading that it is disabled by default, and they seems to be what you see. Actually, is there no activity in either direction? Maybe your core is also not using flow control on your UART. Once you fix this, you should able to run at m...

Re: MIDI NES

Does this MIDI support allow for a keyboard to work with the Miracle Piano ROM? I can get my keyboard to work with the NSF player, but it does not work when I try to use it with Miracle Piano ROM. Yes it works. It requires the Miracle Piano nes file to have a NES 2.0 header, with the Miracle Piano option set in the controller byte. https://www.nes...

Re: MIDI NES

Is it possible to plug a keyboard controller (with class-compliant USB MIDI-out) directly into my MiSTer USB hub to “play” notes in the nsf player? Yes. I tested with a MIDI keyboard using a USB MIDI cable plugged into a standard USB port. Just set the UART mode to MIDI, MidiLink to USB, and open an NSF file (one that isn't continuous [e.g. sfx] i...

Re: Homebrew NES port of the arcade version of Donkey Kong

FYI, in case you're curious, this was implemented here: https://github.com/MiSTer-devel/NES_MiSTer/pull/246/files It added RAM support for all the mappers the code there supports: https://github.com/MiSTer-devel/NES_MiSTer/blob/master/rtl/cart.sv#L154 // Mappers: 0, 2, 3, 7, 28, 94, 97, 180, 185 // So, it's been in place for several months now.

Re: MIDI NES

Here is a video of me demoing it with a Miracle Piano. I think any MIDI source the MiSTer recognizes would work, but the interface isn't super robust, so avoid sending it anything too weird. It really only supports note on/off (with freq number and volume) and patch commands that switch between the pulse duty cycles. https://www.youtube.com/watch?v...

Re: TI-994a How-To

Regarding the Standard/MBX cart menu I don't know if there is code associated to the MBX entry or is just a placeholder. This could be checked with @greyrogue that worked on the MiSTer version of the core. I found conflicting info on MBX carts when working on it. Currently, it treats 0x6C00-0x6FFF as RAM if the MBX OSD option is selected. I don't ...

Re: Miracle Piano on NES core

Found a few minutes to test/fix this. It works again in the release today. Go to the right page of options, Set the UART mode to MIDI, and MidiLink type to USB. It will then play and receive midi through USB MIDI connections on the USB hub if the NES ROM loaded has the Miracle Piano specified in the header. (byte 0xF [dec 15] set to 0x19 [dec 25])....

Re: Miracle Piano on NES core

GreyRogue had added support for Miracle Piano. My understanding is that it works with a USB MIDI (MidiLink). Maybe for PC/Amiga? When it comes to the Amiga I am a n00b. According to the original documents the Miracle Piano hooks up to PC though a proprietary serial cable. There no Midi support on the NES. No. For NES. https://github.com/MiSTer-dev...

Re: Support for large Neo Geo ROM hacks?

I know for certain that there are issues with KOF2004SE. It was only relatively recently that the correct algorithm for encoding audio samples was determined (by Lord Nightmare, I think?). This meant that older ROM hacks used an incorrect algorithm that sounded correct in older versions of MAME, but will have clipping issues on real hardware (and a...
