A list of MSX Cartridge Shop MegaFlashROM SCC+ SD compatibility settings for loading particular ROMs and disk files.
This fantastic cartridge by Manuel Pazos works as a slot expander in slot 1. Moreover there are so many hardware combinations that can create problems with this. This wiki tries to list all the solutions found to solve problems with strange configurations like MSX2 machines upgraded to 2+ for example. It means that if it works on these strange configurations maybe it works fine on standard MSX.
The read-back fix of the cartridge is a feature that emulates the non-conventional RAM access that some software uses. Without this fix software which accesses the memory in a non-standard way doesn’t recognize the 512K ram of the MegaFlashROM SCC+ SD.
If you want to emulate it with openMSX emulator have a look at Emulating MegaFlashROM SCC+ SD with openMSX.

|---|---|---|---|
| MOONBLASTER 1.4 MOONBLASTER PLAYER | /Dx | MAP.COM or other Tricks to make it work with Dos2/Nextor don't work often. If you want a Juke-Box use, you can prepare .FDx disk-set where .FD1 contains the program and othe .FDx contains the music. Then you can flash them with the command line (or a batch file). | |
| MULTIPLE DISK SET WITH .FDx extension | /Dx /N | If you want to flash .FDx disk set from MM it works. If you want to add for example /N option and you choose the command line you must specify the n° of the disk adding the /Dx option before the /N | |
| UNKNOWN REALITY | It works only as music replayer and if you flash disks | It works also from SD and DOS2 |
Here's a list of ROMs with problems that might be confused as an MFRSCC+SD issue (but actually are not):

| Description | Key | Note |
|---|---|---|
| Disable diskinterface MFR SCC+ SD (slot 1) | R | SCC and memory mapper still available |
| Skip MAPDRV Virtual Disk | 0 | If you used MAPDRV on NEXTOR to mount a DSK as a drive. To unmount it delete NEXT_DSK.DAT file |
| Disable diskinterface MFR SCC+ SD (slot 2) | F | SCC and memory mapper still available |
| Enable 60Hz on 50Hz computers | F5 | Temporary enable 60Hz on Non-Japanese computers |
