Template: SurfaceDragon Litewall-9 BattleVersion1
Layout: 128 KB LoROM · 8 KB SRAM
ROM patch: cycle list + 8 direct patterns + first pattern + title/checksum
ALPHA NOTE: the ROM exporter already patches real Litewall configuration. The 24×24 shape sketchpad and SNES-only FX lab are live-preview/project features in v0.1; their cartridge code hooks are the next excavation target.

Pattern cycle listmax 20

This list is real ROM data. Exported cartridges boot with this cycle order after fresh SRAM.

Direct pattern bank8 + first

Matches Litewall's native direct-pattern configuration. The tool also writes a matching 8 KB SRAM image.

PHOTOSENSITIVITY: strobe and high-BPM brightness effects can create rapid flashes. They default OFF. This panel is the browser-side test bench before we wire the equivalent effects into the SNES engine.

24×24 shape laboratorySQUARE

SurfaceDragon documented Litewall shape designs as exactly 24×24 monochrome pixels. This editor follows that constraint. v0.1 stores these in the project and uses them in the live synth; ROM injection is intentionally not claimed until the BattleVersion graphics block is mapped byte-for-byte.

Browser controller mappingGamepad API

These mappings drive the browser preview. The exported Litewall ROM retains its native SNES mapping in v0.1.
