Well, to have expansion RAM would be great in general. 512 K is enought. If you can work with 128 k, the 512 k is nearly the same.
About ROMs, would be great to be able to add expansion ROMs.
However I must admit that I can't check out the emulator here at work, will do that later at home. So maybe I got a bit a wrong picture of it.
Roland emulator has 2 ways for loading software. 1. Loads from the server, with the filename in the URL. 2. From your local storage, dragging a file into screen area.
The first option is targeted to non-experienced cpc-users, that doesn't have dsks or taps images in their hardrives. Also they don't know how to load the software: run", |cpm, so all this will be occur transparently.
The second one is for cpc-users. You can load a local file (like in cpcbox), but also must type the start command.
So I can put a 4th machine: 6128 with 512k. And you can load locally the dsk that you want. Also I can upload some software to the server that uses that expansion.
To add ROM I have this idea:
-You drag into emulator a 16k raw rom file.
-Emulator ask you from bank number: http://www.cpcwiki.eu/index.php/Upper_ROM_Bank_Number
What do you think?
