Help! emulator issue

Fusion Ed · Post by **Fusion Ed** » Sat Aug 11, 2007 8:38 am

Got a problem, wondering if anyone has any ideas?

I have two ostrich emulators connected to a daughter board, the board needs to have the rom begin from h4000, but nistune will only start the rom at h0000. Is there anyway I can offset the emulation so this works correctly. I have tried to see if i can get the rom board to read from the lower half of the maps but its in Japanese so that doesnt really help me!

Any help would be great.

The emulators use the OFFSET parameter in the address file to determine where the upload point should start from

If you look at the 16K address files, the offset for these starts at OFFSET=&H4000 so it emulates the top 16K of a 32K (27C256) EPROM

Hope that makes sense!

Yes it does thanks matt, i'll give it a go tomorrow. Could you not add this in as a feature to choose where to burn it from a pull down menu or something? Several times now it would have been soooo handy to have.

I can add it as a 'manual override' option which will display the memory location in the address file and let you change it. Would that be okay?

Yeah, I just would like an nice simple way to decide what map I'm working on.

For example I open a bin for a pair of 512's I would like to select which one I am working from and then be able to save that bin again as a complete file. Whatever way does that nicely is fine by me.

Matt,

I tried the following:

#UNIT NAME
TYPE_UNIT,Micra K11 CG10DE/CG13DE,*,*,*

OFFSET=&H4000

#ENGINE SPECIFIC PARAMETERS
CYLINDER=4
ENGINECC=998
INJECTORCC=1

#ECU SPECIFIC PARAMETERS
NTLOOKUPID=64

and it didn't work. Any idea what I am missing? If i upload from 4000 using other software and using burnt eproms its fine, so i know that is all ok.

ed, why are offsetting the k11 rom?

I have a grid board, and no documentation (jap) its reading from H4000, I emailed them and was told I needed to offset it in software.

thats odd, i know some japanese k11s use that offset but ours shouldn't?

does it not work with no off-set?

ie rom loaded from 0000 in the emulators?

No, doesn't work at all. Tried that nothing, limp home, so duplicated it into both halfs of odd/even and it worked fine. I just cannot do anything with it as nistune wants to alter the lower half.

Doh!

It is possible for ODD/EVEN mode that it ignores the offset. I've added an investigate item on this one also

ok thanks matt, if you could look into this, and perhaps pleaseee include as an option in nistune so that it all works seamlessly that would be great.

ps. how the boards coming on? I'd like to place an order
