Are there any tricks to get roms bigger than 128 kb working with my setup (in bluemsx)?

Roms are located on the hardrive with loadrom program.
My setup is: msx2, 4mb mapper, sunrise ide, loadrom 1.0.

Games like Contra or penguin adventure work just fine, but Space manbow, Hydlide 3 etc (^256kb-2048kb) roms do not work, but hangs on startup screen.
I guess this is a memory issue..?

Yeah, I could just put the rom in the cartidgeslot and use them like that, but I'm testing different setups as I'm planning to buy mapper, ide and stuff like that.

Loadrom has different problems with some (mega)roms, because version 2.0 has never been released and because roms with extra VDP tricks or SCC songs require more memory when using with Loadrom in stead of simply use the cartridgeslot.

For example, BASIC roms are not supported, you can notice some top flickering with Aleste, some slow passages with SCC cartridges. I had always noticed that in blueMSX without harddisk, so I think that the problems remain the same with the harddisk.

A better option is ExecROM, but you need a MegaRAM.
