// main.c — entry point and memory layout for Nyuller.

//
|
|
// Memory layout chosen for the NUFLI displayer:
|
|
// $0000-$0088: zero page
|
|
// $0100-$01FF: hardware stack
|
|
// $0200-$02FF: buffers
|
|
// $0300-$03FF: system variables
|
|
// $0900-$2000: program code
|
|
// $2000-$7A00: NUFLI runtime image
|
|
// $7A00-$8000: small stack (512 bytes)
|
|
// $8000-$D000: compressed waiting bitmaps and screen attributes
|
|
// $D000-$DFFF: C64 I/O registers
|
|
// $E000-$FFFF: game bitmap (RAM with KERNAL banked out)
|
|
//
|
|
// The program is split into three address ranges so the NUFLI runtime
|
|
// image ($2000-$7A00) is never overwritten by the linker.
