A GameBoy emulator (GPLv2: gnuboy, ported, tested on K3)

The game starts on Kindle Touch 5.0.0, but the virtual keyboard of the terminal there is no reaction.

OK, thanks. I probably won't go much further, though. Since the input is (tried to be) read from Linux input devices (/dev/input/...) and not from Xorg or the console, I'm not surprised that software keyboards do not work. That would probably need a more sensible drop-in specifically addressing the touch input. I'm lacking a test device (and before you collect to get me one, read the following and the time/devotion to do this myself.

Even the K4 will need some adaption w/ regard to key codes, I think. This should be more simple in comparison, but again that isn't a job for me, sorry.

Do you mean the touchscreen doesn't work?

or do you mean you can't load a game.

if you mean you cant load the game:

I hacked the loader script : replace $(getkeys) with ${@}

and call it like gameboy.sh tetris

it will assume you have it in /mnt/us/opt/gboy I think
and roms in /mnt/us/opt/gboy/roms/

Like: /mnt/us/opt/gboy/roms/tetris.g*

Then it will just run the game.

NOTE THE FOLLOWING VERSION EXPECTS THE GAME AND ROMS TO BE IN CUSTOM FOLDERS

NOT THE DEFAULT /mnt/us/opt/gboy

CHANGE IT TO YOUR NEEDS!!!

Spoiler:

#!/bin/sh
#===================================================


# killall -stop cvm launchpad 2>$DN	# use if running via Kite
killall -stop cvm 			# use if running via Launchpad
cd /mnt/us/usr/bin/
eips -c;

HOME=/tmp ./fbgnuboy ./rom/"${@}".g* 2>gnuboy.log
# killall -cont cvm launchpad 2>$DN	# use if running via Kite
killall -cont cvm 			# use if running via Launchpad

If you mean the TS doesn't work -
well, "No," I don't expect it does yet.

Hawhill doesn't have a 5. work required.

Hope that helps

Thank you. You have done a lot. Maybe someone can write the correct boot script.

# killall -cont cvm launchpad 2>$DN	# use if running via Kite
killall -cont cvm 			# use if running via Launchpad

that should work for you if you installed to the recommended /mnt/us/opt/gboy location

called like ./gameboy.sh romName

This looks like an awesome app, and I'd love to try it out, but please could someone tell me how to install it? I've jailbroken my Kindle 3 Wifi, but have no idea what to do with the files I've downloaded from page 1. If preferable/possible, please PM me. Thanks in advance for any and all help.

[twobob]

just to confirm... I tested it via VNC on a 5.

games can be started and the demo watched but input mapping would still need to be fixed as no keys are passed.

Also the FB does not update. (on the eink)
Perhaps a fix for this general FB hogging behaviour will come to light in the future.

: )

excellent, more k4-compatible goodies thanks!

it starts fine on a k4, but yeah the button codes will need some tweaking. i tried tetris, i can move the selection between "1 player" and "2 player" using the fiveway left&right, but can't press start to get any further. it just went into demo mode tho and looks like it runs really well.

in case you don't have them handy, here's the k4 key codes from a text file i saved a while ago...

prev page right 109
next page right 191
prev page left 193
next page left 104
back 158
keyboard 29
menu 139
home 102
centre 194
left 105
right 106
up 103
down 108

edit: my 100th post! watch out geekmaster, i've nearly caught you up...

Okay. One. Tiny question.

well two. kinda.

Q1) how tough will it be to scale up to larger screen size.
Q2) Do you mind if I drop an eips'' in, dirty but effective on the 5.

Thanks. I'm looking in the code now.

[hippy dave]

i think scaling might have been discussed earlier in the thread?

[geekmaster]

And eips works fine on all the kindles, but it may be a bit slow on the K3 and earlier. Fine for testing and debugging though...

Yeah, right! I do almost that many posts in a single day, some days. I would sure like to see you try, though, especially if they contain useful content that increases the usefulness of our kindles.

Yup. but the code has changed some so perhaps the thoughts had changed some. perhaps not

[hippy dave]

ah fair enough

which was how I remember it being left. not highly conclusive...

and I always thought turning the FB on its side might have merit... suppose I may get to find out
