My PICO-8 Adaptor & 2 Migrated PICO-8 games

Hi, here are 2 games I migrated from pico-8 recent.
One principle of migration I set to myself is keep original source code as much as I can. So I made a adaptor layer to emulate pico-8 APIs, which is a big hole I falt into, some features takes me lots of my time. Luckily, they worked, almost 99% source in this 2 games kept as it is(except syntax rewrite).

Both games are full of game elements, especially comparing their code sizes. Worth to read, and study, I think.

1K-Among-Fish
This is a cute small game. Really small, as a game in 1022 Compressed Bytes of code for PICO-1K Jam.

Air Delivery

BTW, some diferrences between pico-8 and MCA:

  • diff resolution: 128x128 vs 160x120
  • no class, all complex struct implement by map/array
  • array in pico8 starts from 1, instead of 0. Include palette
  • pico8 allow function overrides (same name but diff args)
  • priority of operators, /1 > +/- in pico8, vs. |0 < +/- in MCA
  • ^ → **
  • self in pico map object, but Arcade noesn’t support, use static invoke instead.
  • font, 4 * 6 → 6 * 7
  • and many …

The adaptor (see pico8adaptor.ts)

  • Most functions implemented, but not all of them emlated full features, cause there are too many feature to do, and some feature working mode are conflict with MCA’s, so I just do my best to implement them in a generate way.
  • Duplicate one into your project, if you migrate another pico8 game, and then modify or implement functions lacked.
  • Didn’t combin fillp() supporting in SSPR() yet, see world_race_aqee

These games are great. I liked Airdelivery the most but the sprite work and color schemes are amazing!

How do you make these? I asked this somewhere else but I didn’t get an answer.

Pico 8 is a fantasy console not unlike makecode arcade. These games you see are pico8 games ported to makecode arcade

That’s a little complex. It`d be easier to answer if you ask more detail.
