Mirage has released a new version of this cool painting program can support C64 graphics mode with file export in (.PRG) format.

This version needs windows 2000 or higher and dotnet 2.0, which you can download from microsoft.

SHO-FLI (Sprite Hires OVerlay FLI/Sprite OVerlay Hires FLI) is a custom c64 graphic mode which features a hiresolution spriteoverlay in one color over a FLI image.

It works in exactly the same way as the SHFLI mode but the image data is wider due to using 1 sprite overlay (rather than two in SHFLI) – This GFX mode is also known as SHF-XL originally invented by Crossbow/Crest. I created this Application because this gfx mode is rather awkward to paint in.  Plus there does not seem to be any converters released.

HISTORY:

UPDATE 3 – 17/02/09

• Selective ordered dither implemented – now default  Dithers pixels only if they dont fall in the c64 color range.
• White is now displayed as white.
• Ability to select background color (for asthetic purposes only. does not affect the 144×168 image)

Here’s yet another entry for the 1K games category. This time round it is Container for the Commodore C64.

Game Description:

Collect the containers before your energy runs out.

FAT40 and Orion made a VIC20 version of the game Island of Secrets.

The game itself is simple and the parser limited, but the atmosphere is good, thanks also to the excellent manual, with comic-style drawings and nice descriptions.

I held off on announcing uIEC/SD availability until I had some stock (impatient folks, you know who you are , but I do now have some stock 90 units).

Since uIEC shares the same firmware (kudos to Ingo Korb, who does not get enough recognition for this fine piece of code) as the recently announced SD2IEC, I’ll spare everyone rehashing the similarities and just note the differences:

Features:

• uIEC/SD is currently the smallest known CBM drive (1.5″ x 1.5″ by 0.3″). Perfect for embedding in your favorite machine, drive, or calculator (shout out to Tone007, who stuffed one in a CBM pocket calculator)
• uIEC/SD shares the same 128kB Atmel AVR 8-bit microcontroller as the rest of the uIEC line. With 51kB used for firmware, there’s plenty of room left for the future.
• uIEC/SD comes complete for use with IEC connector and power supply cassette port connector. VIC/64/C128 users can simply plug the wires in and use. (SX64/+4/C116/C16 users need to source 5V elsewhere, let me know before purchasing if you’d like an alternate connector)
• Although not yet defined for use, uIEC/SD offers an additional switch line and programmatic LED for future use.
• uIEC/SD not only supports SD and SDHC cards, but either SD or SDHC cards can also be used for updating the firmware (new feature, older firmware update software only supports SD cards)

• YUV perceptual conversion now nearly 5x as fast.
• Displays pixel error percentage of final rendered image in comparison to attributeless 16col c64 conversion.
• Correct extension now automatically appended to filename.

Find your way through the dungeon levels and bring the Amulet back to the surface. Watch out for fierce guardian Demons and other creatures living in the dungeons.

Use the cursor keys to move. Move towards a monster to attack it. Any items are picked up when you walk on them.

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming. Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. They’re reused for this particular PLA replacement in the FPGA Arcade 28 pin DIL CPLD board.

Two approaches exist to build such a PLA replacement:

1. Implementation based on a truth table with 216 entries, each entry consiting of 8 bits and programmed into an EPROM chip.
2. Reverse engineered logic equations programmed into a PLD.

Both approaches result in the same logic functionality when implemented in a CPLD. Since equations are more common for CPLDs, I chose this implementation style for the final design. However, there’s a variant for the truth table available which has been verified in simulation but not in real C64 hardware. Following are descriptions for both of them.

We have run simulations proving that the equations perfectly match the truth table, so both compiled outputs are effectively identical in the C64 implementation discussed here.

Forth, the Language.

Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.

It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.
