There are emulators (for other targets) which do emulate NTSC decoding properly, but until I did the research for this demo nobody understood how the CGA card generates composite signals well enough to be emulate it properly. I have some code which I hope to be adding to DOSBox (and any other emulators that want it) soon.
- acqq 12y agoDo you know, how was the video uploaded to the YouTube made, if the emulators don't work? Was it really recorded with the plain camera?
- Scali 12y agoWe used a real PC obviously (my machine), and a capture device plugged into the NTSC composite output of the CGA card.
- Zardoz84 12y agoThere is a link to download the music of the ASCII credits at the end ? I really like it. Also, I would like to propose a little challenge. What do you think that could do you archive on this "virtual" computer : - Specs : https://github.com/trillek-team/trillek-computer https://github.com/trillek-team/trillek-computer - Implementation/Emulator : https://github.com/trillek-team/trillek-vcomputer-module https://github.com/trillek-team/trillek-vcomputer-module In a short resume : - 32 bit RISC CPU running at 100KHz (to 1MHz) - CGA like text mode, but can be remaped to any desired RAM address and the font can be changed on the fly. Fixed palette of 16 colours - VSync interrupt + two timers - 128KiB of RAM (to 1MiB) - Floppy drive (max 1.2 MiB) Extra : Displaying it against a Commodore 1084S monitor -> http://imgur.com/GuTVEdj http://imgur.com/GuTVEdj
