This is a slightly modified version of Dr.Mario for Atari 8 bit. In this version you can find some bugs fixed and works very well on NTSC machine.

In game keys:

• P – Pause.
• N – Change the music in the game.
• M – Mute.
• Q – Exit the game.
• K – Mute the “clicking” sound.

You can download the game here.

UberCassette is a solution for the archival and restoration of programs on cassette tapes for 8-bit machines from the 80′s.

There are many programs out there for doing this, some of them work, some don’t so well. Many of them work as long as you have an old enough machine to run them on. No other program does many different types, though.

UberCassette supports tape formats for: Commodore C16/+4, Commodore C64, Commodore,VIC-20, Acorn Electron, Acorn BBC, Sinclair Spectrum, Amstrad CPC464

If you are interested in BASIC programming for the C-64, then you have probably used a BASIC Extension at some point.  Most of us are familiar with Commodore’s Simons’ BASIC cartridge.  Unfortunately, most of these extensions aren’t very useful.

Simons’ BASIC, for example, has a pretty lousy set of commands.  Many of them are basically (pun) useless.  It’s also a very confusing set of commands — there are no consistent conventions used, making it necessary to constantly refer to the manual.

Further, a program written with Simons’ BASIC can only be run on a C-64 with a Simons’ BASIC cartridge.  Pretty limiting. DotBASIC Plus is similar to other extensions in one way: you get a lot of new commands (or DotCommands, of course) — over 100 so far.  But that’s where the similarities end.

This is a very old project published in a Dutch magazine to capture the state of the IRQ for Commodore 64 (vic-20) with a LED. After many years i have decided to make it.

On the photo you can see the project and the right connections on the cartridge port.

Components:

• 1 x IC 74LS04.
• 1 x Bicolor LED.
• 2 x 330 ohm resistors.
• Tiny wires.

How it work?

When the CPU generates an IRQ the green LED lights up, otherwise is red, if the irq is turned on and off quickly the led is orange.

Char Pad is a cross-development tools aimed squarely at developing graphics for Commodore 64 games and will hopefully ease and inspire the production of new games software for this immortal and unique platform.

New features:

• Variable tile sizes, currently 1×1, 2×2, 3×3, 4×4 or 5×5.
• Pixel level editing of whole tiles.
• 80×50 and 40×25 map editor modes.
• Map flood-fill + copy & paste any map area.
• Move & Mirror tiles or maps.
• Powerful character set optimizer.
• Collision “material” editing & grouping for easy software collision detection.
• Export any data in raw or PRG formats.
• Load and save SEUCK compatible background files (including Jon Wells’ sideways SEUCK mod).

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer and other devices. Firmware update (27022011):

• This new firmware brings 6581 filter emulation by connecting B0 AVR pin to ground (on the Photo).
• Filter distrortions are still not emulated, only filter cutoff is affected.

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 or VIC20 if you’re feeling brave and have the right kit.

CBM prg Studio is a replacement for C64PrgGen and VIC20PrgGen and is designed to be a single development tool which will cover some of the early CBM 8-bit machines.

Micro ZoomFloppy is a reduced version of the ZoomFloppy interface.

The interface Micro ZoomFloppy will sit in the 6522 IC socket of the Commodore Floppy Drive and provides the complete ZoomFloppy functionality.  The only external connection is a USB connector.
