Dizzy Rainy Day-compatibility problems?

HI all
So,I just did a little list ab\out my game compatibility.
Here's list:
********************************************PC****************************************
Working Perfectly on:
-FCEUX Ultra
-Nintendulator
-Nestopia
-Jnes
-VirtuaNES
-NesterJ
-RockNes
-olafnes


Glitchy,but playable:
-Nesticle(Map is moved half way up)
-NESten(But,other mapper 0 Games is wrong emulated too...(i.e.Mach rider)
-Fakenes(Same as NESten)
-80five(Same as NESten,and Fakenes)

Unplayable:
-UberNES(Sprites are invisible!)

********************************************NON PC:***********************************
Working Perfectly:
-FCEUGX Wii

Unplayable:
-PocketNES(Sprites are invisible!But other Mapper 0 isn't working too!);NES emulator for GBA.
-NesDS(Sprites invisible,again...);Nes emulator for DS

I'm supprised about invisible sprites in some emulators,but I tried other Mapper 0 games (like Mach rider) and they didn't worked perfectly.
So...I just was wondering:
It's my fault?(Invisible sprites in some emulators)
