Title: Has anybody Patched the OS464.ROM to Enable 16 or 32 Roms (Sorted OK)
Post by: Audronic on 12:27, 11 July 19
Hi All

Has anybody Patched the OS464.ROM to Enable 16 or 32 Roms ?
Also.
Has anybody Patched the OS664.ROM to Enable 16 or 32 Roms ?

How do you reset the correct Checksum ?

Thanks Ray

Yes, but I've no idea where they are. Ask @GUNHED (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2029) , I believe he was the one that edited them.

That was using the Booster ROM from the Inicrons. Which contains lot's of space f.e. for ROM management software.

I thought the Booster ROM will only work in slot 15. So a 464 would never see it as it only scans from 7 downwards?

Hi All


I have temporarily sorted the Checksum concern.
I now have the RedBox files checksum back to &4100h and it works.


Thanks to all

You can put it where you want, but some choices make more sense.  :)

Interesting, I always thought it was a 6128 only solution.

Yes, saw that thread already. You say it's V3, but for the 464. I assume this is Firmware and BASIC in one file?
My comment above was regarding the Booster ROM and whether it works on a 464 with MegaFlash (Booster installed in slot 6 or 7 of course).

Yes thats correct.
I was having problems on a cpc6128 with the Booster rom affecting Parados.
Drive unable to read 40 Track disks and weird disk effects .
So I went looking for alternatives to provide the 32 Slots for the 6128 and or the 16 slots for the CPC464.
Booster rom does not work for the 464 as as you have indicated it is unable to work when Placed at Slot 15 ? (Mandatory)


Thanks.  Ray

@GUNHED (http://www.cpcwiki.eu/forum/index.php?action=profile;u=2029) just claimed (5 posts above) that it will work in any slot, not just slot 15? So you've tested this and that's not the case?

The Booster notes that I read said only put it in 15.
So I did.
No I did not try it anywhere else.
To late now .
I have an other solution.


Thanks.  Ray
