Rangi 0af28de791 Fix assertion failure on nonzero base palette ID without an attribute map or palette map 
Also fix palette map IDs to wrap at 256, not at 8 like attributes
 2026-07-19 23:59:38 -04:00
Rangi 8d2275dc48 Use rpnErrorAt wrapper to ensure setting isError on all RPN errors 
Two possible RPN errors were missing `isError = true;`

Rangi 7e11ab4d8f uint16_t tileIdx type matches options.baseTileIDs 
Tile IDs wrap at 8 bits, but that's handled by `uint8_t tileID`

Rangi ba4a7f2e6a Explicitly assume what was verified earlier by readSection 2026-07-15 22:56:43 -04:00
Rangi b0948566bb Fail-safe treat 16-bit alignment as a fixed address even in RGBLINK 
RGBASM does this itself, so should not output sections with 16-bit
alignment, but an invalid object file could otherwise cause
`getPlacement` to infinitely loop.

Rangi 7e2a3491a5 Encapsulate fseek+ftell idiom in seekSize

Rangi 5869e0dc60 Fix RGBLINK scrambling algorithm to work for SRAM 
Since SRAM sections start from 0, we had been using a signed
`int8_t curScrambleSRAM` counter to allow 0 as a scrambled bank,
but this actually just placed all floating SRAM sections in bank 0.

Rangi 196d50c1d7 Add XXX: comment tag to working but fragile test cases 2026-07-13 22:39:41 -04:00
Rangi 8b951bc047 Fix a flaky/random-seed rgbgfx_test test failure 
Commit 21eaa2d2cc missed some
intentional unsigned underflow that is needed to set `nbTilesInBank`.
Without it, some of the randomly-seeded RGBGFX tests, such as
`./rgbgfx_test seed8.bin -b 207 -N 54,256`, can fail with "Color
mismatch after round-tripping" errors.

Rangi 4857ad1e00 Fix crash on image without any colors (all transparent) 2026-07-11 13:18:40 -04:00
Rangi 3b33c942ae Fix a crash and a limitation in RGBGFX unoptimized output 
- If both banks 0 and 1 were completely filled, then
  `assume(bank == 0)` would false and potentially crash.
- If the input image had fully-background tiles, they would be
  incorrectly counted towards `nbTiles` and could cause the
  "Image contains N tiles, exceeding the limit" check to fail.
