Yeah, it is my mistake! When I said 2Mbit, I meant 2MB. Also, when I read your 4Mbit, it processed as 4MB in my mind! I think I need to cool down it a bit! 
MegaRAM can max out to 2 megabytes or 16 megabits.

The largest ROM that I have seen is 4Mb, are there any 16Mb in size? or indeed any in 8Mb in size?

Most of them are games... there are around 10 megaroms with 8mb in size and I do remember 1 as 16megarom (but it was a korean cart with lots of small roms inside).
Carts with 8Mb: some Koei games, Holy Qu'ran, korean cart and others... just check them around (google is your friend).  |

Manuel,
Some MegaRAMs just don't work with TR. I have a TR GT and a DDX MegaRAM (512KB). Some guys replaced the memory chips by faster ones and solved the problem. Other guys did the same and got no results.
My MegaRAM didn't work with my TR until I tried it on my DDX slot expander. It worked! But it doesn't work on any TR slot, it must be on DDX slot expander.
ExecROM or TestRAM just recognizing the MegaRAM isn't enough. They must display its size correctly. Sometimes the MegaRAM is detected, but it can't map its pages correctly or data read from or written to its memory is corrupted, and you just get a "frozen MSX" when running a MegaROM.
You reported that your MegaRAM runs fine on a non-TR machine. So I believe your MegaRAM is ok (if you're still in doubt, run TestRAM).
I don't have any further tip... If you're not willing to use a soldering iron on your MegaRAM, try putting the MegaRAM in a slot expander in your TR.
Regards,
Adriano

Adriano, thanks for your answer, but if you check the 10th post of this thread, you see that I already tried that...

Sorry for missing your post, Manuel. Can you test your MegaRAM with another slot expander? It's weird, I know, but my MegaRAM doesn't work in my TR with my ACVS slot expander, only with my DDX slot expander (!).

Slotexpanders are not so easy to get! 
I think I have another one somewhere, but it doesn't have any casing. |
