Wow, looks like I missed a game out there... And great title screen, too!

I don't think it's possible to create a single .PRG file for this game. It contains several files that all load to the same address (except the last one)

Code: Select all

(cbm) file 0:*
LOADER (SYS850): PRG, size=69 bytes, start=$0352
STAGE1: PRG, size=4098 bytes, start=$1000
STAGE2: PRG, size=1026 bytes, start=$1000
STAGE3: PRG, size=4097 bytes, start=$1001
STAGE4: PRG, size=194 bytes, start=$033c

I think the loader file is used to fetch each one in turn

Code: Select all

(cbm) cat "0:LOADER (SYS850)" | dxa
        .word $0352
        * = $0352

l352    lda #$00
        sta $9d
        lda $ba
        sta l38e
        jsr l372
        jsr $1100
        ldy #$00
l363    dex
        bne l363
l366    dey
        bne l363
l369    jsr l372
        jsr $1010
        jsr l372
l372    lda #$01
        ldx l38e
        ldy #$01
        jsr $ffba
        inc l394
        lda #$06
        ldx #$8f
        ldy #$03
        jsr $ffbd
        lda #$00
        jsr $ffd5
        rts
l38e    .byt $00,$53,$54
        .byt $41,$47,$45
l394    .byt $30

This game has intrigued me for a long time. It reminds me of The Pit and Zorgon's Kingdom (though I'm sure it plays very differently!).

I was just finally going to test it and now see that I only have the tap-version. Where did you find the D64?

I'll post the .d64 file later, I think it's on the FE3 files, looking at the files that are levels so they must load them every time you complete a level,so if you complete level 2 and die you might have to load the first level again?
Cheers for the reply about the memory locations

I've managed to dig out the .TAP version of it (untested), if anyone is interested?
