In my quest to gather as much info on this as I can I found that the creator of the Chip Maestro cartridge Jarek Lupinski made all of his work public on Github. He has some interesting projects on there. I figured I would post them here as a reference. Chip-Maestro https://github.com/jareklupinski/chip-maestro There's a couple other projects on hi...

I have a few MIDINES carts that I'm trying to dump the roms from but I'm having trouble because of the custom mapper they use. I did get a partial dump and was able to have the MIDINES screen display but that's all I was able to do. Also this is the first cart I've ever attempted to dump. I have two different hardware revisions of the MIDINES and ...

Hang On Jr is not meant to be played with digital controls https://segaretro.org/File:HangOnJr_JP_Cabinet.jpg Left and right are a paddle input and the accelerator is a pedal (motorcycle throttle). If you have a paddle and pedal you can set them up in the input menu (osd). Otherwise use analog x and y to control it. You can test the inputs in the h...

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...

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...

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...

TI-99/4A: - Updated framework (adaptive scanlines, shadow mask, 64-phase filter, etc). Updates from Flandango: New M99 Rom Header for easier loading of multi part cartridges. Separated System Roms/Groms and DSRs from cartridge roms. SAMS Support up to 1Meg. Can now load Carts with roms up to 32Megs. Tipi support via User IO port. PCode System Suppo...

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.

TI-99/4A Release
20210829
-Fix speech overflow
- From Flandango:
Disk Support
NTSC/PAL switch
Support for more cart types including Mega Cart
Larger SAM size support
Various improvements

***Note that adding support for more memory and larger carts means this core now requires the SDRAM module to function. ***

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...

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 ...

Awesome, this finally worked for me! :D Now if only I could find the proc'd button! (Is there a keyboard map somewhere for all the special TI keys?) https://commons.wikimedia.org/wiki/File:TI-99-4A_Tastaturfeld.jpg https://www.scuzzscink.com/amiga/scuzzblog_august19_3/car_sbd_260819_02.jpg FCTN key activates the alternate keys. (Left-Alt = FCTN) h...

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])....

I get the same sequence on 6.0 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0xf82934 0x710 0x6f2 0x704 0xf82934 0x70a 0x5cc Interestingly it does the loop perfectly fine earlier on 0xf819c6 0xf819f6 0xf82934 0xf819c6 0xf819f6 0xf82934 0xf819c6 0xf819f6 0xf82934 I'll see what I can dig out. In the meantime here i...

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...

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...
