Once you have the proper hardware to do it safely (e.g. that slotexpander) it is very easy for standard ROMs (like most game ROMs of 32kB and smaller). And quite easy for known ROMs (with a known mapper type). But quite hard if there's a new kind of mappertype involved. Then you have to dump a part and reverse engineer the mapper type from the code.

Here goes some tips on this topic:

CIEL is making new batches of his mini slot expander, but they've been selling like hotcakes, so they get sold out pretty quickly. Keep an eye on his website and his personal Facebook account, since he announces the new batches there.

Tecnobytes also make their slot expander from time to time, so you might want to contact them to put your name on a reservation list.

SuperSoniqs also have their Modulon slot expander, but I don't know if they have any in stock.

ReproFactory also have a mini slot-expander, but they're out of stock right now. AFAIK those don't have the slot-disable switches or BUSDIR implemented, so they wouldn't be useful for what you need anyway.

Why not? Simple, cheap, effective, mod is easy to reverse & cartridges can be left in original condition. Works with any ROM cartridge you plug in. Did this on >1 of my MSX machines over time and never had any issues. Suppose you have five 5 MSX'es and 100+ cartridges, only one mod to one machine needed to dump all those carts.

Quote:

- 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)

That's actually a worse option imho: unless you put some kind of cartridge holder on the cable that 100% prevents cartridges from being inserted the wrong way, using a cable gives more chance of doing that & thus bigger chance of hardware damage.

Quote:

- Plug in the cartridge to the computer while you have power on (May cause permanent damage to cartridge / computer)

Don't ever do that! Evil There's people who claim they've done so many times without issue. But it's still relatively dangerous and easy to cause damage that way. If you're gonna risk damaging your MSX, then better take a cheap model & risk damaging it by doing a small hardware mod. Virtual zero risk anyway if you know how to do that mod.

I inserted a cartridge in a running MSX by accident a couple of times when I was little. The first time I broke a slotexpander. Luckily my father could get it repaired. The second time I destroyed our copy of Contra, much to my chagrin.

Actually only one of them is enough... Naturally some storage device to save the resulting dumps is required also. (If you plan to buy Megaflash ROM, make sure to get the "+SD" model.)

Hi sd-snatcher.
I recently bought the expander from Leonardo Padial, which works perfectly. It is without a box.
Allows external power

It allows to disconnect one of the connectors, to start.
