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:
- Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
- Tabbed MDI.
- Syntax highlighting.
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.
New features:
- Screen designer speed up.
- Speed up of switching/adding/opening files and projects.
Bug Fixed:
- Assembler:
- Duplicate labels not detected in projects.
- SYS call always created at start of file.
- Build order not correct.
- Assembly dump showing both parts of the code within conditional assembly statements.
- Code reformatting issues.
- Negative numbers in BYTE and WORD sequences not assembled properly.
- Numbers in strings in BYTE sequences not assembled properly.
- Numbers in TEXT sequences not assembled properly.
- Arithmetic in WORD sequences not assembled properly.
- General:
- Sprite Designer grid glitches.
- Exception thrown when generating .prg with the output window closed.
- Code indent/outdent/comment/uncomment would add extra carriage return.
- Code comment/uncomment would add extra REM statements.
- Problem adding existing files to a project.

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.

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.

This a special edition of the Commodore C64, celebrating the 1.000.000th sale of the C64 in Germany. This is one of the most desirable Commodore items. There are about 300 golden Commodore C64 produced. The numbers from 1.000.000 until 1.000.100 were for the staff of the Commodore factory Braunschweig.
The rest was given to hard- en software companies, magazine-publishers and distributors. The C64 is a computer system with a keyboard, external power-supply and a motherboard. On the motherboard you will find a MOS 6510 processor, RAM / ROM memory, MOS 6569 VIC-II video chip, MOS 6581 SID sound chip and twice a MOS 6526 CIA. PAL version.
