YMT-Player is a player that allow you to play Project-Ymer YMT files (Windows) on the Atari ST. The program is made by Peter Jørgensen aka. fedepede.
What is Project-Ymer YMT files ?
YMT files are like the YM/AY files. Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player. Up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)
The advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo, when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc, and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc. It is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.

CBM prg Studio Version 3.2.1 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.
CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.
CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.
It was also a good opportunity for a face lift and to add some new features, such as:
What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.

The Creativision console was given to me on loan from a friend, Andrea Pierdomenico for testing the MultiROM v1.0 cartridge made by Treviso RC (Francesco Brolli)
I and Andrea we realized that the power supply was lost (tragedy). The original power supply of the CreatiVision uses 16v in AC 350ma and 9v in AC 1amp.
Here comes Ciro (Ninetyniner Iuc) that months ago gave me a transformer extirpated from a unknown motherboard and with a bit of fortune there are all voltages.
At this point, given the poor quality of the output video via antenna that comes with the Creativision i have decided to make the easy Composite Video/Audio mod and acting on the Trimmer (color gain) native on the PCB of Creativision i have reached a good quality of the image.
I must thank Andrea Pierdomenico, Ninetyniner Iuc and Francesco Brolli (Treviso RC) for the MultiROM Cartridge v1.0.

The Video Technology CreatiVision was a hybrid computer and home video game console introduced by VTech in 1981. The hybrid unit was similar in concept to computers such as the APF Imagination Machine, the older VideoBrain Family Computer, and to a lesser extent the Intellivision game console and Coleco Adam computer, all of which anticipated the trend of video game consoles becoming more like low-end computers.
The CreatiVision was distributed in many European countries, in South Africa, in Israel under the Educat 2002 name, as well as in Australia under the Dick Smith Wizzard name. Other names for the system (all officially produced by VTech themselves) include the FunVision Computer Video Games System, Hanimex Rameses and VZ 2000. All CreatiVision and similar clones were designed for use with PAL standard television sets, except the Japanese CreatiVision (distributed by Cheryco) which was NTSC and is nowadays much sought after by collectors.
The CreatiVision console sported an 8-bit Rockwell 6502 CPU at a speed of 2 MHz, 1KB of RAM and 16KB of Video RAM, and had a graphics resolution of 256 × 192 with 16 colors and 32 sprites. The console had 2 integrated joystick/membrane keypad controllers (much like the ColecoVision) which, when set in a special compartment on top of the console, could be used as a computer keyboard. The CreatiVision had interfaces for a cassette player, an extra rubber keyboard, floppy disk drive, parallel I/O interface, modem (likely unreleased), Centronics printer and one memory expansion module for use with the Basic language cartridge.
The CreatiVision was discontinued in late 1985/early 1986. A computer was produced by VTech in 1984-1986, based on CreatiVision hardware and compatible with most of the games: Laser 2001, which sold in Europe and Australia. It was also available in Finland through Salora, with the name of Manager. The Manager had a specific keyboard with Finnish layout and character set.

Repair Atari Falcon with a dead Keyboard.
Defect:
Repairing:
The defect was caused by a broken track in the third layer of the pcb, thus not visible. Missing the voltage of +5v from the component (L83) towards the pin four of the keyboard connector (J18) (circuit diagram).
I have made a small bridge for fix the problem permanently.
