Launching Gambatte Gameboy Emulator From Terminal

retroarch -L

// if installed on linux mint using
// sudo apt install libretro-gambatte
// then it will probably be at:
/usr/lib/x86_64-linux-gnu/libretro/gambatte_libretro.so

// full command for me:
retroarch -L /usr/lib/x86_64-linux-gnu/libretro/gambatte_libretro.so /home/bweew/Documents/Syncthing/Lsdj/lsdj.gb

f for full screen f1 for settings like changing the key maps

You can make it a bash script

#!/bin/bash
retroarch -L /usr/lib/x86_64-linux-gnu/libretro/gambatte_libretro.so "$HOME/Documents/Syncthing/Lsdj/lsdj.gb"
chmod +x ~/lsdj.sh

//on raspberry pi 3 64 bit os
#!/bin/bash
retroarch -L /usr/lib/aarch64-linux-gnu/libretro/gambatte_libretro.so lsdj.gb

mediaboy - great for making music roms on gameboy easily

mediaboy releases

the music export is the most useful.
says it can do .mod and .uge but its not working for me
the gif and video exports work in sameboy but not on my flashcart or in gearboy
pcm samplerate settings:
9198 hz -GBVP2 parity yeilds best quality
DMG gives clearer images than colour it seems to mangle the image with blocky pixels
to

goomba paletted

use that with gameboy slideshow generator instead of that because it screws up the audio

making gb and gbc videos worked better flashed directly with gb flasher to a perfect dark cart instead of on the superchis gba sd cart also sameboy and bgb are more accurate usually but goomba breaks

renaming png and jpgs as numbers using bash

How to make full size lsdj videos like aquallex

lsdjhd

tommitytom, the maker of retroplug made this web player that lets you view all the screens of lsdj at once.

finally a linux native retroplug for lsdj

retroplug dropped 2 weeks ago

update has a standalone, vst2, vst3, clap and commandline version
also works with nes

use retroplug-cli lsdj-rom --split channels flag foroutput

new renoise2 mod linux native with terminal use

keyd - key remapping on linux

keyd github

I wanted to be able to switch layers or something to map keys in a different localization to be able to use extra shortcuts.
--renoise doesn't detect f13 - 24 making this whole thing useless for my case. but its still a nice key remapper

Installing

git clone https://github.com/rvaiya/keyd
cd keyd
make && sudo make install
sudo systemctl enable --now keyd

Finding Keystrokes

keyd monitor

Listing Available Keys

keyd list-keys

Editing The Config

sudo vim /etc/keyd/default.conf

reload config

sudo keyd reload

play wavs on gba with gsm play

gsm player

couldn't get in pogoshell

heres my bash script using sox to convert mp3s to wav and then open the converter

#!/bin/bash

for file in "$@"; do
    output="${file%.*}.wav"
    sox "$file" -r 22050 -c 1 -e gsm-full-rate "$output"
    wine "ps2gsm_linker.exe"
done

gba multi cart and mod files made easy with pogoshell

Pogoshell loaded up some of Randall's sick jungle protracker mods

for f in *.mod; do wine dcmp.exe "$f" "${f%.mod}.mdz" && rm -- "$f"; done

that uses dcmp from the tools dir to convert .mod to .mdz to save space but it sometimes screws them up really bad lol
