A question from a new MSX2 owner
I forgot, I hope this question is legit... If it isn't you can close the topic, but I hope somebody can tell me something 
As far as there are also many public domain / freeware ROMs, I don't see any problem regarding your question.
You can try to execute the ROM files using some MSX-DOS tools, such as loadrom, romload, execrom, odo, etc.
Keep in mind that probably you won't be able to run any megaROM (games >64 KB) or, at least, not properly. In order to emulate a cartridge you need additional hardware, such as MegaFlashSCC, MegaRAM, Konami SCC+, etc.
On the other hand, some megaROMs were converted to be loaded in a regular MSX2 computer with at least 128 KB RAM. That should work fine without further ado in your computer, but probably they are not *legitimate* copies 
Enjoy your computer!
you got one problem maybe and that is the 360KB single sided drive this prevents you to load a large ROM of 512 KB into an SCC+(Flash type like mentioned before)
if you have a 8235 with a 720KB disk drive you are lucky....
the 8245 has a double sided disk drive like the most msx computers
