Re: BeebSID

Please, if there's anyone else out there with an Electron (even if you don't have a SID), please could you try running the original orcanpeet.ssd from the post above and we can try and get Lee up and running No Electron but MAME can emulate this setup. With Plus1, AP5, BeebSID, and SEDFS I get the ...

Re: PACE COMMSTAR 1038Ver. E1.10 (16K ROM Image)

I saved this Romimage from my PACE Commstar extension for the Acorn Electron. PACE COMMSTAR 1028Ver. E1.10 fits in an 16K EPROM (27128). I think it is a pretty rare version and hopefully it will be of use for someone in this group. Thanks, already have E1.12 so this is a nice addition. Also good to...

Re: MAME: Click (and other large ROMs)

So does the original PAL switch on 0x3fe0, just wondering where this came from?

If you decide to replicate any of the other PALs, you can be confident that my switching zones are correct. Just note that the Watford ROMs only switch the top 8K. You may have a customer for TED if pixelblip likes it.

Re: MAME: Click (and other large ROMs)

It may well work. However, the 0x40 & 0x60 zones definitely exist in the PAL. I'll also try removing them from the PAL, and see what happens. Seems to work with only: /* switching zones for Inter-Word */ switch (offset & 0x3fe0) { case 0x0060: case 0x3fc0: m_bank = 0; break; case 0x0040: case 0x3fa...

Re: MAME: Click (and other large ROMs)

It appears that the InterWord PAL has additional switching as follows: offset 0x3FC0 (switches in bank 0) offset 0x3FA0 (switches in bank 1) offset 0x3FE0 (switches in bank 1) I think this might be why you're seeing issues with the BBC. I saw similar issues when just using the 0x40 and 0x60 switche...

Re: MAME: Click (and other large ROMs)

I notice from your code that you've only applied this logic (to only switch to higher bank if already in bank 0) to the ccispell ROM type. I wonder if this logic should also apply to the other CC PALs (eg ccibase)? Applying the same logic to Inter-Base does not work, but is definitely required for ...

There have been countless improvements to BBC and Electron emulation in MAME (MESS no longer exists) over the past couple of years, so anything older will have plenty of known issues.
