VirtualC64 v0.9.6.1 for Intel Macintosh OSx

June 27th, 2012 1 comment

VirtualC64 emulates a Commodore 64 personal computer on your Intel Macintosh OSx > 10.6.

I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Bug fixes and enhancements:

  • Lions native fullscreen mode now works as expected (no more ugly borders)
  • Removed old fullscreen mode which frequently crashed on lion machines.

SID Known v1.04 a SID tune identifier tool

June 25th, 2012 No comments

SID Known is a command line tool (M$ Windows) which you can use to identify SID tunes from SID and PRG files.

This tool can be used if e.g. you want to know which SID tune is used in a specific C64 demo or C64 game, or you have a SID tune found or ripped and you want to know if it is already in your SID collection.

EasyFlash Cart Builder v1.00

June 12th, 2012 No comments

EasyFlash Cart Builder is a M$ Windows tool for linking files together into an EasyFlash cartridge.

This is the first release of the EasyFlash Cart Builder. This release is capable of building a valid EasyFlash cartridge image that utilizes both EasyAPI and EasyFS. Cartridges are define in an XML file format. Each cartridge must define a boot image which must be a 16K Ultimax cart image.

If you want EasyAPI included in your archive you need to include the standard EAPI marker at offset $3800 of your boot image.

Ym2149 Tracker 12.023 Beta

June 8th, 2012 2 comments

Peter Jørgensen has released a new Beta version of his YM-2149 Tracker for M$ Windows. The sound chip YM-2149 is used in Atari ST/E/Falcon series.

New Function in Beta 12.021:

  • Auto portamento.
  • Buzzer Vibrato.
  • Buzzer portamento.
  • Unified frequent list.
  • Turn Tone/Wave on-off in vibrato, bend and arpeggio.
  • Vibrato Depth.
  • Invert Vibrato for synth wave.

Beta 120.23 – note from the author:

i found 3 bugs in the tone-bend routine. and i have also change 2 of the functions in the program.

Before note-lock was affecting both S1 and S2 now you can set it to s1,s2 or both. I have also change bend-mode ramp-off to only turn off the source that is being bent. So if you bend only S1 then it is only S1 that is turn off after the bend is finish

AspeQt v0.8.3 (Atari serial peripheral emulator for Qt)

June 3rd, 2012 No comments

AspeQt is a cross-platform, free and open source Atari 8-bit serial peripheral emulator. The name is an acronym for Atari serial peripheral emulator for Qt, Qt being the cross-platform application development framework used by AspeQt.

AspeQt emulates various Atari 8-bit peripherals like disk drives and printers via an SIO-2-PC cable. If you are familiar with software like Sio2Pc, APE, Atari810, AtariSIO etc., you probably won’t have any problems getting used to AspeQt.

Even though AspeQt is not fully mature yet, it is easy to use and, despite its shortcomings, has many features that you may find useful, the highlights being:

  • Cross-platform GUI with drag and drop support.
  • 8 emulated disk drives with support for 512 bytes per sector disk images.
  • High speed operation up to 6 times faster than the normal speed.
  • Ability to use PC folders as emulated disks.
  • Disk image explorer for viewing and modifying disk image contents.
  • Ability to run Atari executables without messing with disk images and DOSes.
  • Printer emulation.
  • Cassette image playback.

HxC Floppy Emulator: Software updated

May 31st, 2012 No comments

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.

The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).

There are two differents emulators:

  • A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
  • A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.

Release notes for the HxCFloppyEmulator software v1.6.11.16:

  • Akai S950 DD & Akai S950 HD interface mode support added (need firmware v1.6.4.4 or more)
  • … full release notes here

Sidreloc v1.0 by Kryo/LFT

May 29th, 2012 No comments

Sidreloc is a tool for relocating SID tunes any number of whole pages, using a novel but remarkably simple algorithm. It can also relocate all zero-page variables used by the tune.

Sidreloc is capable of relocating 91% of HVSC #56 out of the box. Many of the remaining tunes can be relocated by tweaking the settings to fit them.

While the tool is SID specific, the fundamental algorithm could easily be adapted to relocate all sorts of 6510/6502 machine code that meets a couple of requirements (see “Observations” below).

Sidreloc is primarily a linux program, but it’s open source (MIT license) and you are encouraged to port it to different operating systems. Good patches will be merged into the official version.



CCS64 v3.9

May 29th, 2012 No comments

CCS64 is a Commodore 64 Emulator for PC developed by Per Håkan Sundell.

CCS64 is shareware. This means that the program is free to use and to copy, but if you like it and use it regularly I would appreciate that you would register the program.

CBM prg Studio v2.3.0 released

May 25th, 2012 No comments

CBM prg Studio Version 2.3.0 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 or VIC20 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 in v2.3.0:

  • Support for the C16 and Plus/4 machines.
  • Undo/redo for character, sprite, and screen designers.
  • Support for illegal opcodes.
  • Screen designer added to C128 platform (40 column, c64 mode only).
  • Start page.

Major bugs fixed:

  • Commodore key (in screen designer) producing wrong code for certain colours.
  • PI keyword not recognised.
  • DATA keyword coloured incorrectly.
  • Occasional duplicate start address in new project wizard.
  • Wrong link address for VIC 20 projects in generated SYS call.
  • Renumbering programs with no destination line numbers after GOTO, GOSUB etc.
  • Lowercase text not handled correctly by ‘text’ directive.
  • Some minor MMI issues.

XSidplay2 v2.1.2

May 20th, 2012 No comments

XSidplay2 is a QT based music player for SID music.

It is based onto Michael Schwendt’s XSIDPLAY, the historical SID player for Linux, actually no more developed by the author.

from the author:

This version implement a runtime libraries selection (for now however, it must be used one library in one executable as there are some more name conflicts to remove).

It now uses libsidplayfp with resid 1.0 by default (resid-fp emulation will be added in next versions). Consider this as a testing version, so please report bug or issue you find in it.
