From 0c54a19a0b482e5498c0c95ab1588731d34623d4 Mon Sep 17 00:00:00 2001 From: Oliver Schmidt Date: Sun, 20 Aug 2017 11:49:02 +0200 Subject: [PATCH] Adjusted to recent driver interface change. The change is inspired by the code of the standard joystick driver. It is however absolutely untested. Note: Sites like http://raster.atariportal.cz/english.htm state that there needs to be a delay when reading joysticks via the MultiJoy adapter. There's no such delay in the driver. But I don't dare to decide to add it. --- libsrc/atari/joy/atrmj8.s | 21 ++++++--------------- 1 file changed, 6 insertions(+), 15 deletions(-) diff --git a/libsrc/atari/joy/atrmj8.s b/libsrc/atari/joy/atrmj8.s index 46766070b..0e8cd2a0a 100644 --- a/libsrc/atari/joy/atrmj8.s +++ b/libsrc/atari/joy/atrmj8.s @@ -35,17 +35,6 @@ .addr $0000 -; Button state masks (8 values) - - .byte $02 ; JOY_UP - .byte $04 ; JOY_DOWN - .byte $08 ; JOY_LEFT - .byte $10 ; JOY_RIGHT - .byte $01 ; JOY_FIRE - .byte $00 ; JOY_FIRE2 not available - .byte $00 ; Future expansion - .byte $00 ; Future expansion - ; Jump table. .addr INSTALL @@ -115,10 +104,12 @@ READJOY: ; Read joystick - lda PORTA ; get position - and #%00001111 + lda STRIG0 ; get button + asl a + asl a + asl a asl a - ora TRIG0 ; add button information - eor #%00011111 + ora PORTA ; add position information + eor #$1F ldx #0 ; fix X rts -- 2.39.5
