Commodore-64

Unijoysticle 2 C64 add Bluetooth gamepad functionality to the Commodore 64/128. For those familiar with the Unijoysticle 2+, this is the evolution of it. Features: One gamepad controls one Joystick or two gamepads control two Joystick or one gamepad controls two Joysticks (for Dual Stick games) or use Wii Steering Wheel or use Wii Balance Board Supports gamepad rumble for certain games Supports C64 GS buttons (2nd and 3rd button) for C64 GS games Supports additional 4th and 5th buttons (Select + Start) button for certain games ...

Unijoysticle 2+ For those not familiar with Unijoysticle 2, it is a device that allows you to use modern Bluetooth gamepads like Sony DualSense or Nintendo Switch controllers (to name just a few) on old computers like the Commodore 64 or Amiga. What’s new in version 2+: Case friendly: lower profile, LEDs & buttons are close the border and has mounting holes. Looks nicer: Uses SMD components for almost everything Supports buttons 2 & 3 in port #2. Some Amiga games might use them. Cheaper to manufacture. I reduced the price from $60 to $35

https://www.youtube.com/watch?v=nCzAlfXOOXo “Amor para Dos” is a multi-platform 256-byte intro. The binary, without any kind of modification, can run both on: a 80386 (or better) + DOS and on a Commodore 64. We ( L.I.A) released it at Flashparty 2021. I did the coding.

Announcing Unijoysticle 2: Use modern Bluetooth controllers (gamepads, mice, smart TV remote controllers) in retro computers like the Commodore 64/128, Atari ST, Amiga and more. For further info go here: /unijoysticle2

With PVM with released an intro for the Tandy 1000 HX. The Tandy 1000 HX uses the Intel 8088-2 CPU. Which is a suuuuper slow CPU (slower than the 8086). With all its wait states and its limitations on the video card (no hardware sprites, no charset redefinition) it makes it comparable with a Commodore 64. In fact, for certain things a Commodore 64 if way faster. Without further ado, this is the Tandy intro: ...

I’ve been busy. I still have no spare time to work on my retro projects, but I have a plan. And it can’t fail. I plan to port the UniJoystiCle + The Uni Games to the following platforms: Commodore VIC 20: UniJoystiCle (single joystick) + The Uni Games Commodore PET: UniJoystiCle in expansion port (single joystick) + The Uni Games Commodore 128: UniJoystiCle (same as the C64) + The Uni Games in VCD mode using the Z80 CPU Tandy 1000: UniJoystiCle + The Uni Games (graphics mode 320x200 16 colors) Commodore 64: Add paddle support to the UniJoystiCle

A few months ago we released the Argentine Songbook Vol. 1 chipdisk. And recently we released its source code including: Full source code (the assembly files + makefiles + everything…) Full audio sources (the SidWizard files) And we also wrote a tutorial about how write a chipdisk, including all the tricks that we used. C64 Assembly Tutorial (english) C64 Assembly Tutorial (spanish) Full source code If you have doubts/questions about it, let us know! ...

Two weeks ago I attended the Commodore Vegas Expo XII, and last week I’ve been at the Vintage Computer Festival West XI. CommVEx XII As the name describes it, it was a Commodore Expo in Las Vegas. But the format is a mix between conference and expo. It is a real expo, but with the social part of a conference. It is friendly and casual. People give talks in a very informal way. I gave a talk + live demo about the UniJoystiCle. Everything went well except that in the middle of the demo my phone’s glass broke. But that wasn’t an issue since the accelerometer kept working.

As a kid, I always avoided the Drean Commodore. I didn’t like them because they were not compatible with the NTSC software. As an adult, I really wanted one basically because I’m from Argentina, and the Drean was produced in Argentina. And I want to make sure that all the software that I develop works on a Drean. And in my lastest trip to Argentina I was able to get one :-) The condition of the computer is Ok, neither great nor terrible. It works, although I need to do more tests. Here are some photos:

MOS 6526: The CIA chip You turn on your beloved SX-64 and you don’t see the blinking cursor. Don’t panic. Most probably one of the CIA chips (MOS 6526) is not working correctly. [caption id="" align=“alignnone” width=“400”] No blinking cursor[/caption] The Commodore 64 has two CIA chips. What you need to do is to replace the one that controls the keyboard, the CIA 1. But if you don’t know which one is CIA 1 and which is CIA 2, then you can either replace both, or do trial-and-error, or look at the IO schematics (hint: it is the one with the UB3 legend). As far as I know any MOS 6526 should work: MOS 6526 (found in the very first C64s) MOS 6526 R4 (found in newer C64s) MOS 6526A (the 2Mhz version, and I read somewhere that it works Ok) So, in order to get the replacement chip, you can get it on eBay, or extract it from another another C64 or SX-64. The MOS 6526 chips on a regular C64, are located at the top-left corner. [caption id="" align=“alignnone” width=“400”] I removed the 6526 from a regular C64[/caption] I suggest using a chip extractor to extract the chips, although a flat screwdriver can work as well.
