Ahh. Since the driver sets up what each bank means and handles the switching you should be able to pull that data by other means. You may end up not even using a core bank then.

Ggghhhh. Have you seen sms_mapper_w? It reads like stereo instructions. That's kind of lame that whatever it is that SMH_BANK does can't be manually invoked.

That said, I think I have a lead, so... yeah.

Edit: Heck with it. I can't, for the life of me, figure out what it wants. Someone else can hook up the 93C46. It doesn't help that Meka's source code is harder to read than Greek.

And...before you ask, no, start address is equal to 0 smirk


Well, the size on a real Xi is 800x400 (80x10=800, 25x16=400) so I don't know where the 640x375 comes from. Is something assuming a character cell is 8 pixels wide and 15 high?

640x375 is the calculated MAME/MESS resolution from the MC6845 video core. I highly suspect that's wrong and you're right though, it's not even the first time that core betrays me...

JD, with the code changed on SVN rev. 6261, variable "smsvdp->prev_bitmap_saved" is not necessary anymore. I was working on adding view modes for 3-D games, then updated the patch, attached it to bug 70 and included the changes to remove that variable. Please take a look on the patch.

also, I think I left a smsvdp->tmpbitmap which was not necessary in the struct. feel free to remove it as well.


@JD: please move debug feature in CDI to CONFSETTING in place of DIPSETTING... dipswitches should only be the ones physically present on the hardware wink

Is it possible to change a CPU's clock speed at runtime in MESS?

Probably it is not the correct thread, but I have fixed some of the problems in the GBC palette, this resolves some problem reported on bugzilla and make the graphic more clean.
