Assigning more memory in E-UAE

[mauidj]

I am using E-UAE via Hi-Toro on my MacBook Pro.
I have a problem with DPaint IV. (and 5)
I keep getting a "not enough memory" message when I try to use anything over 800 x 600 resolution.
Also I can only get a 1 pixel brush to work.
I am guessing this is a memory issue but i can't seem to assign more to the program.
Any ideas?
Many thanks.
Aloha!

What have you allocated in memory terms in DPaint, ideally you need both more Chip RAM and some Fast RAM. UAE can have upto 8 MB of chip ram ( 6MB more than a real Amiga).

@pjhutch

In the Hi-Toro interface I am allocating 2MB of chip and 8MB of fast.
If I allocate more than 2MB to chip it automatically takes the fast to zero.
It allows the allocation of up to 8MB of chip but with zero fast.

I have tried all the combos available using the HiToro control panel with basically the same results.

BTW...really like your site...lots of very useful links.

If memory serves me correctly setting chipram to beyond 2meg will make it so you cant assign any fast ram. You can however still set z3 fast ram to as high as you like regardless of the amount of chipram. You may need to manually alter your config file if HiToro doesnt have an option for zorro3 fast ram. Havent used it for a while, but I think its set with "z3mem_size=32" (or replace 32 with the amount of fast ram you want to assign (and no quotes)).

fishy_fiz,
Your memory is working just fine.

2meg of Chip and you get no fish...I mean Fast  ;-)

Yes, Hi-Toro allows you to add 512meg of Z3 fast RAM. And 32meg of RTG Graphics RAM.

I just tried that with 8meg of chip...zero fast.
But with all of that I still get a "not enough memory for this # of colors" and a single pixel brush  :-?

I wonder why I can't assign more chip RAM while keeping 8meg of regular fast RAM?

It's a technical restriction, but not an issue as you can use zorro3 fast ram anyway, and as far as the "amiga" is concerned pretty much the same thing. As for your problem, Im a little confused. Firstly there is no resolution above 800x600 for AGA (unless youve made custom screenmodes) and in fact there's not even an 800x600. Only 640x512 or 1280x512 come close to those, and both of those can be used in any color depth, apart from 1280x512, which cant use Ham8, and thats only if using the default 2 meg chipram. Having said that though, page size can be bigger than screen resolution. Are you using custom chipset graphic modes, or RTG ? If youre using RTG (uaegfx) then you need to add some RTG memory. Just out of interest, how big is the image youre trying to load into Dpaint, and how many colors are you trying to view it in.
