This was after some beer, so please don't be surprised or scared :) There is even some Finnish at the end ("terveydeksi").

DOSBOX can capture DRO files on AdLib register changes. This is a small and stupid program written by me which can play it back on Commodore 64 if it is equipped with an SFX Sound Expander cartridge (with YM3812 chip though, otherwise no OPL2 ...). I don't have that hardware either, so I can test only with emulator (but others told me it works ...). The tune is captured from Dune I game. Note, that VICE (the C64 emulator) may not emulate the hardware correctly so there can be minor glitches, I should have the real hardware to be able to tell :)

I'm trying to speak some Norwegian here, quite awful. So you have been warned!!!! Also I am very nervous in case of any kind of public stuff, I can't even speak my mother language (Hungarian) too well then :)

This a hand-shaking free :) [thanks to Youtube] version of the original video here: https://www.youtube.com/watch?v=iJwvp6lZ2DU
http://cubed-borka.blogspot.hu/2017/04/mega-65-emulating-8080-cpu-and-running.html
This is a little project from me, emulating an intel 8080 CPU on Mega-65 only "from software" to be able to run CP/M applications. Here, original Microsoft BASIC-80 binary MBASIC.COM runs (CP/M version). Note about the bad cursor position. And sorry about the shaky video, but I have no tool to put my phone on, and I had to type as well somehow :) The error message at the end is normal, since there is no BOOT/WBOOT CP/M BIOS call emulation yet, just to be demonstrated the "unhandled trap" in my emulation code.

Xemu mega65 test. Note about some hardware problem at the end with intel GPU and Linux :) It's out of scope of Xemu though, this shitty notebook wanted to shut down itself because of overheating meanwhile, maybe too much for recording the desktop and using Xemu at the same time. The reset near at the end in fullscreen mode already was done by me. The problem with disk chooser is maybe the fact that disk image related registers are not emulated at all, yet :) This version already uses 28 bit linear addressing at emulator level. The percent value in the disk window title is the running/sleeping ratio, ie it's better to have this value as little as it can be, over 100% means: no real time emulation is possible. No M65 fast mode yet, it was at the speed of the average C65 clock speed. M65 logo can't be shown because no proper 16 bit text mode support for VIC-IV is implemented yet (the stripe at the end would be probably the end of line $FFFF markers).

Home built scanner for the C64 from 1992, built by Arpi (the guy sitting at the computer - he is also the main author of MPlayer, btw). "Try to use it again" party in 2011. The design is "interesting", it uses a LED to shine through the paper and a photo diode, using some motors from cars (used to move the windscreen cleaner ...). We're using Commodore 128 now (in C64 mode though, so who cares). More photos: http://gabucino.be/files/c64scan.html
