Nice try :)
I was thinking about a GEOS implementation but it would require a jump table at $C000 :(

Ultimem BLK6

Hi!
Does Ultimem support RAM at BLK6?

Re: Emulation problems with Power-20 (split from: "WIP: Arukanoido")

Indeed, the calibration hangs.
By the way my Trojan light pen has no trigger, maybe there should be a fallback. How about the shift key?

Re: Emulation problems with Power-20 (split from: "WIP: Arukanoido")

Mike, I found the cause of the problem: It's the paddle emulation!
Paddle sets joystick left.
Light pen sets joystick left and right.
Strange...

BTW Power20 includes a 1351 emulation, funny.
However my Vice 3.0 is very slow...

Re: Emulation problems with Power-20 (split from: "WIP: Arukanoido")

No point patching a program to work with a defective emulator. Please try out your Power20 with this simple BASIC program. It reads out the joystick with essentially the same method as shown in the WIKI , just it uses 37137 (=$9111) instead of the more easier to remember 37151 (both registers work ...

Re: Emulation problems with Power-20 (split from: "WIP: Arukanoido")

At least I made a patch

Code: Select all

a36c1
,36C1:  EA        NOP
,36C2:  EA        NOP
,36C3: 
g
it may help with other buggy VIAs.
Please go on!

Emulation problems with Power-20 (split from: "WIP: Arukanoido")

When the hardware check shows up, Arukanoido actually scans memory for add-ons. (There'll be one for the Ultimem expansion at least.) Power20 hangs at 08 >36BC: 36 00 6F 02 FB nv-BdIZc LDA 9111 >36BF: 34 6F 6F 02 FB nv-BdIzc AND #10 >36C1: 36 00 6F 02 FB nv-BdIZc BEQ 36BC >VIA1 Zustand (Versatile I...

Re: unexpanded vic .cfg file for cc65

In version 2.16 cfg/vic20.cfg looks like MEMORY { ZP: file = "", define = yes, start = $0002, size = $001A; LOADADDR: file = %O, start = $11FF, size = $0002; HEADER: file = %O, start = $1201, size = $000C; MAIN: file = %O, define = yes, start = $120D, size = $6DF3 - __STACKSIZE__; } SEGMEN...
