@mrdoornbos Yes, exactly.

@Logiker464 So prg minus 2?

Last weekend, last few days - before Christmas and the Vintage Computing Christmas Challenge ❄️ 2025! Deadline 24th Dec 2025. logiker.com/vccc2025 #sizecoding #vintage #retro #vccc2025 #BASIC #assembler #6502 #z80 #advent #apl #MerryChristmas

@mrdoornbos You can use the smallest of 3 sizes: Source, file and executable size. In your case prg is smaller than the source. For the executable size you can take the file size minus headers. On the C64 you have a header of 2 Bytes for BASIC, which is the load address.

@Logiker464 My prg is actually smaller than my txt file (BASIC) size. Do I use the prg size?

@geehaf 5% is a lot. Who knows, maybe some more until Christmas Day.

@Logiker464 5% reduction in byte size achieved....I think it's time to wrap it up and submit.

Submissons for the Christmas Challenge 2025 are open. But take your time. You still have time until at least Dec 24th, 18:00 CET. logiker.com/vccc2025 #sizecoding #vintage #retro #vccc2025 #BASIC #assembly #mos6502 #z80 #advent #apl #MerryChristmas

@joeyvc64 Crushing or being crushed, that's the question. And it might be a logical or.

@Logiker464 Just uploaded mine. Let's see how much I get crushed this year...😬😅

@circuit_k I can't predict the numbers. I assume there will be less, for two reasons: 1. As you said, the shape is not easy. 2. Social media is more divided these days then it used to be. Let's see, what the outcome will be.

@Logiker464 I've submitted two already. Are there more contenders than last year? The shape is definitely more difficult.

Juiced.GS sponsors a one-year-subscription for their mag. That's 4 printed issues! Thanks a lot! Maybe this will be an extra motivation for some Apple II coder! Christmas Challenge 2025 logiker.com/vccc2025 #apple2 #sizecoding #vintage #retro #vccc2025 #BASIC

@geehaf That's the hardest part...

@Logiker464 Now to start the optimization process...
