The Nintendo Wii console featured a "Virtual Console" section in its online store, which featured a total of 17 Master System titles over its lifetime. (No other Sega 8-bit systems were supported.) This page gives some of the details of how this was achieved.

Apart from where mentioned above, filenames seem to match GoodSMS names (commonly found on the internet) with almost all non-alphabetical character removed. This suggests that all of the ROM images were obtained from the internet rather than from Sega's internal archives.
Some of the games have text-based patches, apparently to remove flashing and red cross imagery - which is a registered logo of the Red Cross in many countries, and thus a potential legal liability, despite also being widely considered a symbol of medicine/hospitals.
>0x7ff0 string "TMR SEGA" >>0x7ffc belong 0x5250024f 0x0007b8: byte 0xc9 # boss defeat flash skip
The first two lines confirm the ROM image matches. The last one adds a ret
opcode to skip the flashing effect when a boss is defeated.

The patch inserts an alternate mild flashing colour table (white and pale yellow) and edits a pointer to use it in the aforementioned place.

Translation:
The patches change the appearance of hospitals in the game, by changing their external appearance from a red cross to the letter "H", and removing red crosses on the inside:

This is especially tricky because the data in question is actually compressed; the patches modify the compressed data in such a way that it changes the uncompressed result. This is helped by the fact that the shape of "+" is similar to "H".

It seems to be detecting the two ROM variants known (v0 and v1) based on their headers, and patching them both - but only v1 is included in the Virtual Console app.

The flashing effects are all reduced from maximum intensity to minimum intensity (i.e. colour value 1 instead of 3 per channel). The comments all show the previous values. The red crosses in the village hospital (the icon and the nurse's hat) are changed to the letter H:
