Bread Box - Frodo 3DS
Code:
_____               _    _____

3DS Port of Frodo by Spinal_Cord - http://socoder.net/?blog=spinal
Based on FrodoDS ported by GPF - http://gpf.dcemu.co.uk/Frodoc64.php
Based on Frodo by Christian Bauer - http://frodo.cebix.net/

Nobody wanted to port a C64 emulator to the 3DS, so I gave it a shot.

Code:
_____              _____
|  |  |___ _ _ _   |_   _|___
|     | . | | | |    | | | . |
|__|__|___|_____|    |_| |___|
You need a way to run homebrew applications on your 3DS. See
http://smealum.github.io/3ds/ for details.

Be sure to place BreadBox.3dsx and BreadBox.smdh in /3ds/BreadBox/
Any games you with to load should be placed in /c64/games/

Current version ??

Update!
Added joystick directions to the configurable buttons, so you can set X to Up for example.
The upload is too big for gbatemp as it now has the latest source and resources, so here it is - http://socoder.net/uploads/124/BreadBoxEverything.zip


Added
o CIA version
Very important, a DSP dump is needed for this version to work.
I have a mirror of DspDump.3dsx in the files below, be sure to
read up about it here - https://gbatemp.net/threads/release-dsp-dump.423860/

o DPS Audio
o Nicer UI
o 01_6_16 fixed Shift key bug, added cmb and ctrl key functionality to the keyboard.
Working
o Keyboard
o Floppy Drive - I only added support for one drive, shouldn't really need more
o Switch true 1541 support on/off. Some games need it
o Loads .FSS, .d64, .t64, .prg from /c64/games/ folder on SD card
o Swap joystick ports
o Reset
o Save snapshot
o Start button menu!

Most up to date OLD version is available at GitHub. Both 3dsx and source.
https://github.com/spinalcode/BreadBox

The latest version is now attached, should be working fine on all systems and compatible with a lot of games.

If you publish the sources on github (or other place) I could help with sound reusing what i already did for Handy3ds.

But for a good sound it needs to run fullspeed. How is the framerate respect the original?

Love the keyboard on the bottom screen.
So nostolgic!
Key press sounds would be funny to hear though.

Reminds me to dig up some old C64 games, its been too long.

Looking rather good already, keep it up.

I'm not clear on how to open a PRG; I assume I touch the disk drive, but touching a program/pressing the buttons doesn't seem to do much then. Pressing A makes the emulated C64 enter "RUN" and then everything locks up. I assume this is the crash you mention in the topic post, so I'll look forward to future versions.

FYI, the release bundle includes a bunch of Mac OS hidden files; e.g. a __MACOSX directory, ._.DS_Store files littered around. For anyone using this, you don't need those files, they're like windows thumbs.db and desktop.ini files: OS features, unrelated to anything you need to do on 3DS.

Thats not the crash I was talking about. if your .prg doesn't load, then it simply doesn't load. Try a different game. Frodo compatibility is not brilliant because of the emulation methods used.

[edit] Forgot to mention, the C64 screen is 22px taller than the 3DS screen, so I used the 3D Slider to scroll the screen up and down :-P

Wow, impressive! How well is this expected to run on O3DS systems?
I understand there's not a lot to work with given the hardware but I really don't know how resource-intensive C64 emulation is.
Either way, great job!

I only have a 3dsxl to work with, it's running at a good speed without frameskip although there is no audio yet.

@spinal_cord Could you give a step-by-step process to how we should expect to launch software? On my end, touching TRUE 1541 seems to freeze the emulator, as does attempting to mount a d64. I'm not sure I'm even reaching a point where Frodo's compatibility would come into the matter, it doesn't seem like the emulator ever gets far enough to start reading software from D64/PRG. Do PRGs need to be mounted before launching, or do we just hit Load? Should the emulated C64 do the old LOAD "*" (haha, I typed Load "@", force of habit), because currently when I try to Load a PRG the emulated C64 goes directly to RUN. I'm just not certain if I'm loading games correctly and bumping up against crashing, or if I'm doing something wrong to cause my problems.

EDIT: By the way, that's a really cool trick with the 3D slider, nice work.

My most nostalgia inducing computer of all time. So many good memories of tripping to Babbages w/ my dad to pick up the latest Epyx masterpiece (for $4.99!). Thanks for taking up this project, and sharing your work.

@spinal_cord Sorry, behavior seems worse on my end with the new build, any touch events at all seem to freeze up the 3DS and require a hard power off.

On the upside, I've figured out my problem getting PRGs running on the original release; I was attempting to launch clean (i.e. uncracked) PRGs; cracked PRGs for Bubble Bobble, Sensitive and Wizball are all working great. Sorry for the false report.
