Thread: [posted] Commodore C64 Emulation on a Teensy 3.6 Microcontroller

    Impressive work! This really shows off what the Teensy is capable of.

    I also noticed when I look at the code, that your CPU core is based on the 6502 emu I wrote some years back. Nice to see it making the rounds.

    I've made a 3d printed case for the Teensy64 and added a battery, usb charger, amplifier and speaker. It's basically a mobile c64 now, which explains this SX64-II on the case.

    I'm happy to add the STL / Fusion 360 files to the repo if wanted.

    I am also thinking to made one. Just gathering basic stuff now.

    BUILD doc sheets

    Here is a zipped set of build notes from Frank_B as DOC files : FrankB_C64.zip

    Hi gang! I am going to do a presentation on the Teensy64 at the Commodore Retro eXpo (CRX) event in a couple of weeks. See: www.crxevent.com

    Has there been any progress made on making this NTSC compatible? That is a huge issue for us in the U.S. as basically none of the U.S. games work in PAL mode.

    Also, I see that J-M made a neat addition with the virtual keyboard, but his github reports as being 3 commits ahead. Is there an executable of the latest build?

    Thanks!


    Jim

    Did someone test the touch screen support code on the real Teensy64 hardware?

    In the meanwhile, I ported few other game console emulators (on my modified pinout!) but it should not be too difficult to have them running on the Teensy64 hardware board

    Hello, everybody,
    I (really) needed a long, relaxing break.


    I still have some circuit boards, but I think that due to the customs duties only the shipping within Europe makes sense.


    With time I will surely finish long announced c64-updates (esp. VIC)


    Please excuse my long, unannounced absence.

    @Retro_Peter, bitte sende mir eine Mail.

    If there are open questions about this other of my projects or libraries, please don't hesitate to ask again.

    Edit: I've disabled the PMs, so please use eMail (there's a link in my profile)

    Hm trying to compile with Arduino 1.8.7 and Teensyduino 1.44 shows this Error(?) (or warning?) :
    Error while detecting libraries included by C:\Users\Frank\Documents\Arduino\libraries\Teensy6 4_new\Teensy64.cpp

    ...trying to find the reason (Is anyone familiar with this message?)

    Is it just a typo? "\Teensy6 4_new\" has an extra space in it.

    That 'space insertion' shows regularly on Forum posted paths for some reason

    @FrankB - there was some change in Library parsing or limiting of old libraries that resulted in some errors. It was one of the fixes just put in the IDE - it may be catching something in the C64 build? Paul pointed to the 'arduino_debug.exe' versus starting 'arduino.exe' that might shows some added feedback?

    Indeed, the additional space was inserted by vBulletin.
    arduino_debug.exe shows no additional output.
    Well, it seems to work, so it might be a warning - but, funny is, I'm the only one who gets this message. Google knows nothing, and shows this thread only...

    At least it builds and works.
    Would have been nice to see added info from _debug. Here is the recent thread where that was noted with regard to the library issue that came up.

    I'm yet to finish the little box for my Teensy64 (with LCD), but the other day I got this thing from a fellow C64 nerd Just as an inspiration of what can be done. An original casing and with Raspberry Pi as a central unit, Arduino (for the built in emulator menu and operating system) and a keyboard/joystick interface board etc. I guess the same thing could be done with the VGA version of Teensy64 - even though the small size really should be taken in consideration and be used as an advantage (not put inside a big and bulky C64 case ).

    @zonkt: wow this is awesome. can you post more pictures?

    @all: The T3.36 has not headroom for significant improvements regarding the VIC and other low-level things. I tried, but wasn't successful. There is a slight chance when we overclock to 256MHz- but we will soon reach new limits.
    Currently, my plan is a transition to the comming T4 which will be _much_faster and has more ram. Maybe we can use a better display, too.
    My plan is a board that supports other emulators, too, or maybe has small joysticks on board, and a small speaker and allow headphones.
