Obvious ports of NES games

[Sik]

The other day I was playing Dragon Ball Z Super Saiya Densetsu, which is a port of a NES game... and let's just say that I guess they reused the original code because WTF? Sprites are small and have chunks vanishing at the top of the screen, and there are scrolling glitches in the overscan area when you move around. While there are obvious improvements (more colors, better instruments, some simple parallax in battle scenes, some mode 7 scenes) they didn't even consider fixing the obvious stuff?

Are there any other SNES games that are obvious ports of NES code?

Super Mario All-Stars. Tetris & Dr. Mario.

Ninja Gaiden Trilogy.

Super Mario All-Stars.

How much of it is a direct copy? I mean, they did manage to mess up some of the mechanics in the SMB1 port (namely the fact that if you run horizontally and jump to break a brick above you, it will kill your horizontal velocity), so they must've reimplemented at least parts of it.

Final Fantasy IV has a clear NES influence in how the sprites are drawn, especially how they disappear on the left edge, even when the SNES has the technical ability to do that cleanly.

Dragon Quest I&II as well as Dragon Quest III were remade for the SNES, but I don't think many elements of the NES games were re-used, they are complete remakes instead.

Mega Man: The Wily Wars is a collection of the first three Mega Man games for the Sega Genesis. Although there are some graphical changes, the gameplay is pretty much exactly the same as in the NES versions.

Looking more about actual ports of the original NES code (i.e. the original code being used on the SNES rather than having been rewritten from scratch).

Has anyone checked the games listed here to make sure that this is the case of ANY of them?

I have not personally checked All-Stars, but I remember reading reports of where others have disassembled All-Stars, and there's plenty of vestigial stuff in the ROM. ShaneM might be able to explain in more detail.

The vast majority of games mentioned here are remakes, so that rules them out.

The one I mentioned in the first post has the kind of glitches you'd expect only from a NES game though. On top of that most of the graphics (i.e. anything that isn't mode 7 or parallax) are pretty much the same as their NES counterparts, just with more color shades (and all mode 7 scenes are pretty much just animations isolated from everything else). This is why I suspect they just used the code from the original NES game instead of rewriting it, that seems too absurdly close for a remake.

All-Stars is full of 6502-specific code too, like "clc \ adc #1" in place of "inc a"

Final Fantasy IV spent half its development life on the NES. It was up-ported to SNES at some point, rather than being built from the ground up for SNES.

Go search through any game by Bandai. I remember thinking the same about the first few Gundam games on the SFC... aside from the shading, those were totally NES-sized graphics.

I have to imaging Dragon Quest V was the same, because that game is only marginally better than an NES game in terms of graphics and music. However, it does have an amazing story, so that makes up for it. But Dragon Quest VI ... so much nicer at demonstrating what the SNES was capable of.

I don't know if I'd call it obvious, but SimCity was (apparently fully) developed for NES, but only the SNES port was released.
