Hi guys, I took iq_132's partially done Zaxxon/Congo Bongo driver and spiffed it up a bit. So far you can play Congo Bongo with the joystick, but without sound(s).
I noticed that the game needs PPI8255. Is it worth continuing on with the driver without that? How does one emulate it?
Any idea how to get the sound working?
Feel free to post any changes here in this thread, maybe we can have a shared driver-learning experiance :)
How-to install in the fba code: copy this driver to src/burn/drv/pre90s/ then edit makefile.burn_rules, search for d_zerozone.o, and add " d_zaxxon.o" behind it, so the line looks like:
d_zerozone.o d_zaxxon.o \
Save & run make.
best regards,

Heh, I was wondering when you'd find the thread with the crapload of half-finished drivers in it.

A quick glance at the zaxxon.c MAME driver will give you more info about which sound cores and samples are required for the games if they are not a part of FBA you would have to Port em across as for the PPI8255 maybe it's a communication device for the CPU's??
it really does seem to be needed as it's a part of quite a few operations in the zaxxon.c driver again you may have to port it across from MAME
here's the currant MAME driver for zaxxon.c
http://mamedev.org/source/src/mame/drivers/zaxxon.c.html (http://mamedev.org/source/src/mame/drivers/zaxxon.c.html)
this machine src file seems to be related to the ppi commands

FBA has PPI8255 emulation already, there are a fair few drivers that use it.

Thanks for the heads up Treble Winner - I guess I got so caught up multitasking so many different things that I had overlooked it.
I am hoping you guys would try to finish this one, I have so many things on my todo list right now its driving me bonkers :eek: :p

Yuppers. Very unfinished. I don't even remember what all it needs. I need to start documenting things better when they're wip.
-
i'll try to add zaxxon =) also where is the unfinished driver thread ?
-
some fix done, not really perfect but now IN2(coins+start) is working for zaxxon and super zaxxon.
starting sound job using mame samples.
-
Sounds good :) Can't wait to play it in FBA w/sound :D

That's pretty wicked! Nice work! I'd be interested in seeing it in motion. ^^

just a side note the driver was updated on mame 0.162 :
-zaxxon.c: Use SN76489A for sound as shown on congo bongo
