Who's ready for... guess that game! ;D

Post by 0xC0DE » Fri Mar 29, 2019 2:40 pm

Just for fun! And maybe learn something along the way. From which game is this? :mrgreen:

Code: Select all

.play_losing_a_life_tune
        STX     L0076
        STY     L0077 ; 77:76 points to tune data
        LDY     #$00
        STY     L0089
        LDA     (L0076),Y
        STA     L008A ; get number of notes to play (pairs of pitch+duration)
.play_next_note
        LDY     L0089
        INY
        LDA     (L0076),Y
        STA     sound_param_block2+4 ; set pitch
        INY
        LDA     (L0076),Y
        STA     sound_param_block2+6 ; set duration
        STY     L0089
        LDX     #lo(sound_param_block2)
        LDY     #hi(sound_param_block2)
        LDA     #$07
        JSR     osword ; SOUND

        DEC     L008A ; still notes left to play in this tune?
        BNE     play_next_note

        RTS

.losing_a_life_tune
; tune of 16 notes, each note is pair of pitch+duration
        EQUB    (end_losing_a_life_tune-losing_a_life_tune)/2
        EQUB    $21,$04,$29,$02,$21,$04,$19,$02
        EQUB    $15,$04,$05,$02,$0D,$04,$01,$02
        EQUB    $05,$0C,$05,$01,$0D,$01,$15,$01

It's Alphatron.

Are you disassembling it so that you can rebuild it into something a bit more playable. ;)

Yes, it's Alphatron! No plans to disassemble that yet. Too many other little projects cooking :D

I've got more "guess that game" challenges lined up, so more to come!
Would be fun to see similar challenges posted here, so join right in if you want.

Guess that game... from a specific sound sample! (Hint: it's from the Electron version of the game).

It's not from Exile is it? The sound made when an enemy expires, perhaps the robots or birds?

My first home computer was an Electron and that sound is tantalisingly familiar, but I don't know if that's just my imagination playing tricks on me!

(Although it occurs to me that I only ever played Exile on the BBC...)

It's not Exile.
Let me give you all a hint.
This is the colour palette used by the game:

That colour palette is very reminiscent of Repton but it sounds very much like something from Uridium (not that I've ever seen it on the Electron).
Just remember kids, Beeb spelled backwards is Beeb!

I also thought Shark but dismissed it after checking. Now realised you're doing Electron versions only so Shark it is.

I was thinking either Moon Cresta or Star Striker. On a plane so can't check either.

Nope! None of the above.
It's not as obvious as it appears to be.
