To be perfectly honest with you, I wanted to have a third option on the bootup screen. The option would've been this: ??????
Once you had beaten Megaman 1 & 2, the question marks would reveal Megaman 3. However, I could not add Megaman 3 for one simple reason. Megaman 3 uses CHR-ROM, where-as Megaman 1 & 2 use CHR-RAM. Either MM1 & 2 would have to be CHR-ROM, or MM3 would have to be CHR-RAM. Granted I converted MM2 to CHR-ROM, but MM1 was only converted to CHR-ROM in my Upgrade Patch, so I couldn't use it. It had to be a simple CHR-ROM conversion with no other alterations, since the games had to be the original un-altered versions.
In fact, I had even thought to call this Wily Wars for the NES (much like infidelity's SMAS for the NES) if I was able to include Megaman 3.
I have not entirely ruled out the possiblity of re-doing my CHR-ROM conversion of Megaman 1, using the MMC5 mapper and not altering anything else, much like I did with MM2.
Anyway, thank you for letting me know that this works fine on another hardware device.
And yes, if infidelity hadn't done SMAS for the NES, I would not have been inspired to do this, much less think to do it.
I might make Wily Wars for the NES in the future, if I'm able to re-convert Megaman 1 to CHR-ROM.
