You need a way to turn on the MSX without starting the cartridge you want to dump. Then you can dump it with your MSX, using a tool like SAVEROM.COM.
The other way is to use an EPROM burner to read the contents of the EPROM of the cartridge. But this requires opening the cartridge and taking out the EPROM chip (which may be soldered).

I thought if I insert msx-basic floppy will load to it even if there is a cartridge in the slot

There are lot of options to skip booting of a game cartridge in order get it dumped:

- Some (mostly utility cartridges) have a build in method to prevent booting -> See manual (Works in really rare cases)
- Build a switch to disable /SLTSL signal in to the cartridge (I can't really recommend)
- Build a switch to disable /SLTSL signal in to the computer (A bit better, but not too pro option either)
- Build an extension cable for the cartridge slot that has the switch on the cable. (Good since does not cause permanent changes to game or computer)
- Use Slot expander that has switches to enable/disable slots (Requires some MSX shopping)
- Use flashROM cartridge, SRAM cartridge with battery backup or similar on lower slot that has code installed to skip the boot of upper cartridge. (Requires some hardware & two slots on computer. Code can be found somewhere on this forum.)
- Update the firmware of the computer to have number key or similar mapped for skipping certain slot boot code (I've done this for one of my computers, but implementation requires quite a bit of know how, EPROM burner etc.)
- Plug in the cartridge to the computer while you have power on (May cause permanent damage to cartridge / computer)

There are also few possibilities using EPROM-burner:
- Disconnect the ROM chip and connect it to EPROM burner for dumping (Usually very unpractical and you can easily break something permanently)
- Build cartridge -> EPROM adapter that you use in between the cartridge and EPROM-burner. (This requires also some knowhow. I have somewhere such adapter though I've not build it or used it ever)

- Buy a slot expander with switches (slot ON/OFF).

I tried today to boot the floppy with a cartridge inserted it didn't work
I think the slot expander with switches to trick the computer is the easiest way to go
Where to buy this slot Expander??

Or I should just buy a Mega flash rom cartridge I was thinking i need one anyway
Another question please about the extra 512 kb memory version is this gonna allow me to play every single msx game on my msx2 machine ?? Because some discs i made didt load or restarting my computer at certain point i think its memory problem

Fitting slot expander may be a bit hard to get... AFAIK ATM no one is making such, so you need to find used one... I saw one on eBay for 110€ but it was meant to be mounted for PC case... So not the best one, if you plan use it regularly on table.

MFR is good and I recommend getting 512KB version especially if your MSX has only 64KB RAM. Will it make every single MSX game work? No, unfortunately not... I've heard there are few individual games that require even more RAM (mostly Japanese language text adventures), some games require MSX2+, MSX tR, some extension or similar. but the biggest problem is that there are lots of games around that just have memory related or other compatibility problems (=bugs)... Usually the problems are more likely the more old the game is. In such a case it is good idea to look for alternative versions / fixes from internet, but even that may not always help. If you want to read more about these issues, work arounds etc, please look here: https://www.msx.org/wiki/MSX_compatibility_problems
