Hello.
I have a NMS8280 Pal and a MFR SCC + 512K + SD. (I've also an old MFR SCC) Smile
These days I was trying to run R-Type, but both the ROM and fix for the old MFR, I can not get it running at 60hz.
The MultiMente syntax I use is "OPFXSD R-TYPE / U" and is the only way the game works, but always and only at 50HZ.
Try adding the "/ H60" option to the command line, but it is ignored.
Try to hold F5 on startup but do not swap at 60HZ.

I also wanted to ask why when I load on a flashROM a ROM game, the MSX logo is repeated twice.

Thank you. Smile Smile

I have tried the original R-Type ROM and works fine here.
I don't need to add /U option. OPFXSD detects the R-type ROM and selects R-Type mapper.
Also, I can switch 60<->50Hz holding F5 or not

Perhaps you are using a hacked version of the ROM. Try the original ROM or another modified version.

If you add /U you are disabling the subslots. So the cartridge boots in normal mode, disables the subslots and reboots the computer.
Bear in mind that when using /U option your MSX will change to 50Hz when booting, and all changes you have made using F5 or /H60 will be reverted.

I have used many rom of the game, but the result is always that, also with rom fix for old MFR.
About the holding F5 on boot, it never work on any game.
Somehow i've find a method for 60hz to boot R-Type. I've dump the game on multirom opf, together Space Manbow and Manbow 2, so i can select 50/60hz from menu.

Inside MULTIROM.OPF i've wrote:

R-TYPE.ROM /U
Spacem~1.rom
Manbow2.rom /U

So all works fine. But is it right way?

PS. After dump this multirom.opf the logo MSX show three times!!! O_O

I have tried again. This time using a 8250 (quite similar to your 8280).
The games boots fine. No need to use /U option.
Also F5 switchs to 60 Hz.

I tried most ROM games, dumping them on MFR. Nothing work on 60hz when holding F5 to boot.
The games work on 60hz with option "/h60" or SofaRun, then my NMS8280 work on 60hz refresh.

Maybe a bug on my MFR?

probably hard-coded in the ROM you have

What recovery version are you using? Those features are available since v1.4 (almost 4 years ago)
