; Fibonacci sequence in RGBDS Game Boy Assembly (RGBASM)
; Computes successive Fibonacci numbers using WRAM variables

SECTION "Variables", WRAM0

FibPrev:    ds 1    ; Previous Fibonacci number
FibCurr:    ds 1    ; Current Fibonacci number

SECTION "Main", ROM0[$150]

Main::
    ; Initialize: fib(0)=0, fib(1)=1
    xor a
    ld [FibPrev], a     ; FibPrev = 0
    inc a
    ld [FibCurr], a     ; FibCurr = 1

    ld c, 8             ; Compute 8 more iterations

.loop:
    ld a, [FibPrev]     ; a = FibPrev
    ld b, a             ; b = FibPrev (save it)
    ld a, [FibCurr]     ; a = FibCurr
    ld [FibPrev], a     ; FibPrev = old FibCurr
    add a, b            ; a = old FibCurr + old FibPrev
    ld [FibCurr], a     ; FibCurr = sum

    dec c
    jr nz, .loop        ; Repeat 8 times

    ; FibCurr now holds fib(9) = 34

.done:
    halt
    nop
    jr .done

Contribute — propose a file extension

Tell us where to find evidence about RGBASM (mapped to pl/rgbasm). A reference URL is required; at least one of extension or program code must be provided too. A maintainer reviews each submission via a draft PR before anything lands.

File extension (optional) — e.g. .oak. Some PLs (e.g. esolangs) have no convention; leave empty if so. Friendly name (optional)

Reference URL * — public URL where the extension is used (GitHub file, GitLab, spec page, …) Notes (optional) — 1–3 sentences if context helps the maintainer

Optional: attach a program from that URL

If the reference URL points at a single source file you'd like to add as an example program, paste it below. The workflow will write it under languages/RGBASM/programs/<sha>/. Keep under ~200 lines.

Title (optional) — e.g. "Factorial", "Quicksort" License guess (optional) — MIT, GPL-2.0, …

Code (optional) — paste verbatim bytes from the reference URL

(or open the pre-filled issue directly)
