Start:
    inc $ff10,x // Beat up some TED register
    lda $a5     // Read 60 Hz timer
    and #$07
    tax
    // Memory here (at $0532) contains the bytes
    // 10 F6
    // corresponding to
    // bpl Start
    // causing the code to loop.

// Depending on how you look at it, this can be regarded
// as either an 8-byte or a 10-byte intro:
//
// - Payload (Lovebyte compo rules definition):  8 bytes
// - Bytes in file (load address + payload):    10 bytes
// - Code executed (could be located anywhere): 10 bytes
