0.4.1

• Custom font compatibility
• Support games with their own rendering loop through "flip". Save states for these games will not work yet.

Compatibility fixes

• stat(table) should behave like stat(0)
• printing backspaces
• stop looping SFX after length mark
• tonum("") should return empty instead of 0
• time() should go in exact intervals based on frame rate instead of the actual time.

0.4.0

This update mainly focuses on the switch version:

• switch: Move all application data (cartridges, savestates, etc.) to /switch/switch-p8 to reduce clutter.
• enable pico-8 saves without needing a specific folder setup.
• splore: add a context menu accessible with "pause" (button +) to save a BBS cartridge to the local SD.
• local cartridges: add a context menu to delete cartridges from the local SD.
• add animation to splore cartridges

Fixes

• implement pico-8 load() function, a function that loads external cartridges.
• avoid skipping too many frames

0.3.2

• Fixes

  • fget(_, nil)
  • tostring(float) was not showing the correct number
  • tonum(nil) crash,
  • str[number] indexing was returning null.
  • split() would convert "-" to "0"
  • min() and max() with nil values
  • pairs(nil) should return an empty iterator

• p8scii

  • inline binary characters (\^.)
  • inline hex characters (\^:)

• Cartridges used to try these

• Predefined functions
  • pack
  • pal with table
  • tline

0.1.0

This release focused on improving compatibility. For this a major refactor was done, heavily modifying Lua to accept syntax differences on p8lua, and having every number in 16-bit fixed point (just as the real pico8).

Srand + random also have the same behaviour as the original pico8

• p8lua
  • Improve reliability of many transforms (if shorthand, bitwise operators, unary operators, assignment operator, etc.)
  • bitwise operations with decimals
  • add missing assignment operators (e.g. |= &= etc.)
• draw
  • fill patterns
• detect incompatible cartridges (avoid crashes)
• show warning icon when an error happens in lua
• add saves - To enable them, create the /data/p8-saves folder
• predefined functions
  • sget
  • sset
  • clip
  • cartdata
  • dget
  • dset
  • memset
  • fillp
  • pget

splore.0

This release adds a new (quite unpolished) screen on the main menu, that fetches the top 32 featured cartridges from Pico-8's BBS and lets you load them:

Note that compatibility is still very limited - From today's list only 4 were playable. It will improve over time.

• Improved render performance by ~15%
• Fix framerate control (on PS4 it wasn't targetting 30/60fps)
• Added new page on main menu to load cartridges from the featured Pico-8 BBS
• Polished music stability.
