Play MIDI files with GR8NET

For midi conversion I use this python script in linux:

#!/bin/python3
import mido
from pathlib import Path, PurePath

for f in Path('.').rglob('*.mid'):
	print(f.relative_to("."))
	fileExt=f.suffix[1:]
	fileName=str(f.relative_to(".").with_suffix(''))

	min = mido.MidiFile(f)
	mout = mido.MidiFile()

	mout.tracks.append(mido.merge_tracks(min.tracks))
	mout.ticks_per_beat=min.ticks_per_beat
	mout.type=0
	mout.save(fileName + "." + fileExt)

The more complex stuff for midi playing is offloaded to the GR8NET so you can get so decent speed on 3.5Mhz as well.

It is fun to hear the Monkey Island theme playing on you MSX!

Nice work! Too bad my GR8NET is based on the M25P16.

I still have two chips left and have no problems placing them.

They're both reserved now.

There's one more chip available.
@Eugeny. The previous chip replacements went very well

@Eugeny,
I successfully flashed the POF file from the gr8net-fpga-full.zip archive (dated 2020-02-19 12:24)
The owner's firmware was still outdated so _flinfo did not work. I updated that to flash version v.0.12 (2022/7/5).
Then I ran reflash.asc through all 8 steps.
The engine is V.0.10 (2020/1/3). That's the POF file I flashed, I guess?
Eitherway, I get a warning in the POST screen:
Warning: FPGA and flash chip firmware versions mismatch, please update both to the latest.

I'd like to know how to get this straightened out. Thanks.

I have also updated mine some time ago. I think I more or less followed the procedure described here without a problem.

Is your chipset replaced already? You need it for your projects

If you want to sell the GR8NET, please let me know as OPL4 ins't needed in my case

Thanks for the update midi.com and the new demo.
I would also like to thank you for giving advice on how to place the new memory chip W25Q128 (16MB one) in the GR8NET cartridge.
