Does anyone have any information on how these titles were ported from the NES/SNES? I assume that the originals were coded in assembly language, and that would be a massive challenge to convert to completely different hardware.
Were any other NES/SNES titles ported over to the PSX? -- perhaps some Japan-only releases/titles
In theory, emulation could include a combination of machine language interpretation and translation, with tweaks to graphics, instructions, etc, making the porting process much easier and faster. Don't forget that the PS hardware was originally developed FOR Nintendo, and there may be software tools developed (and since improved) by either Nintendo or Sony in-house at that time just for this purpose. Such tools (or clones of such tools) could also easily move to third parties as programmers move from company to company.
