Need help editing Sonic 1's title screen!

Hi, I am having trouble editing the title screen. 

I can't find the sprite mappings (if there are any!)

SonMapEd won't let me export without them.

Please help me?

If it helps, i'm using the ReadySonic rom.

 

Map_obj0E:
    include "_mapsobj0E.asm"

mappings


Nem_TitleSonic:    incbin    artnemtitleson.bin    ; Sonic on title screen
        even

art

This is the Big Sonic Object

above it is the foreground art

 

It depends WHAT exactly on the title screen you want to edit.

If you're looking to edit the placement/look of the emblem, to edit the art, you can just use the preformed tiles to the left in SonMapED and place them in a line for exporting, allowing you to edit them in some other program to your liking. However, to map the tiles (if it's required for what you want), since the mappings are plane mappings, I suggest using PlaneED or some program of that kind.

If you want to edit Sonic on the title screen, the mappings file is 'Title Screen Sonic' in the _maps folder.

EDIT: Whoops. Seems I'm a bit late.

 

Oh, I didn't make it clear. I wanted to edit the SONIC text (Foreground).

 

Below all of Obj0E's code is Obj0F's code (Press Start Button) Below all the code is maps for OBJ0E & Obj0F. Around the Foreground art you'll see it's art

 

Did I also forget to say i'm using a disassembly?

 

located almost at the end of sonic1.asm is


Eni_Title:    incbin    mapenititlescr.bin    ; title screen foreground (mappings)
        even
Nem_TitleFg:    incbin    artnemtitlefor.bin    ; title screen foreground
        even
Nem_TitleSonic:    incbin    artnemtitleson.bin    ; Sonic on title screen
        even
Nem_TitleTM:    incbin    artnemtitletm.bin    ; TM on title screen
        even
Title Foreground mappings is Enigma compressed.

I did direct you in the right direction cause in the same area where Titlesonic is is where the mappings are. some mappings are in .bim format and is compressed.

(man i need to work on my project as well...)

EDIT: i'm not sure if you're suppose to uncompressed it first before editing

 

The mappings for title screen emblem are NOT in .asm, but they are Enigma-compressed.

You can try to download GetArt.NET (used to port PNG, JPG and BMP to MegaDrive's umcompressed art and make palettes and mappings (binary, uncompressed) for it), port title screen image you've made in it (you need to make palette line for it first) and ta-da! Ready art. Compress art into Nemesis, compress mappings into Enigma and replace all files. If you have wrong mappings, set up them via PlaneED or (recommended!) SoniPlane.

If image doesn't show up correctly or game crashes, blame me in this topic and follow guidelines above.
