Which memory expansions with more than +37K are you using?

I've got the Ultimem/VicMIDI – but I'm wondering which other expansions would be worth supporting.

Am not a fan of that area. In fact banked BLK5 is what I'd prefer at the moment.Main issue: an application program is not supposed to do any accesses into I/O 2/3, for whatever reason. You have no way to ensure, whether there is RAM, ROM, or read/write sensitive I/O which can do anything else than store data. It could perform a reset, change the banking scheme, erase the flash memory, etc. IMO, the only legit user of I/O 2/3 is the cartridge firmware in question. Nothing else.
Näääh! I want to play digis via NMI with no extra interface in between.That being said: the only other widespread cartridge I know which supports more than +32K +3K RAM is FE3. There, you could use the FE3 RAM Disk to have an abstracted interface for data storage. It could be worthwhile to port this RAM Disk driver over to Ultimem.
Passt scho. Kenne hier nur eine Spaßbremse, die wahrscheinlich bald das Kamener Kreuz am Bande bekommt, fürs Aufmischen des Forums. :/Edit: Ich weiß, ich bin da eine Spaßbremse. Aber hier steht das gleiche auch schon.

Should be easy to find out the culprit. For now, there are not too many candidates out there. While we're at this ... http://sleepingelephant.com/ipw-web/bul ... 90&start=7, and to quote from there:beamrider wrote:so that's why my MegaCart settings keep getting corrupted

I thought it was +37K?Back-to-topic: Personally, I don't mind using RAM in IO2/3, but such a program will not have the luxury of being used in the real world by a lot of people. 35K expansion is already pushing it and most people only got those to be able to play "Doom". I take full responsibility for talking Kweepa into using 35K back then.

No it isn't. Just +35K flat.I thought it was +37K?
I don't see any problem in this. First, both Mega-Cart and FE3 (<- there, fingers crossed though) provide this RAM expansion and are widespread enough to make use of this RAM expansion option a viable choice. Second, even with 'of-that-time' equipment, +35K are possible with a cartridge extender hosting one VIC-1111, two VIC-1110 switched for BLK3 and BLK5 and one VIC-1210. Or any other 3rd party cartridge.tokra wrote:I take full responsibility for talking Kweepa into using 35K back then.
Perfect match!MCes wrote:BLK5 banked?
