     1) General Info

This is a hack of Tokkyuu Shirei - Solbrain.

It alters the protagonist in gameplay and cutscenes so that you can play as the Shatterhand protagonist in Solbrain.
I never liked the look of the character in Solbrain but always wanted to play that version for its unique stage and different bossfights.
So, I decided to make this hack, put Shatterhand in Solbrain.

What was changed:
- All gameplay related frames for the protagonist, the base one + the full robot transformation
- Pause menu mug shot
- Stage select frames
- Intro and outro art related to the protagonist

Everything else (the look of the robot modules, "points" instead of "coins" etc remains the same as in the original Solbrain).


     2) Patching

Made for and tested with this rom:

Tokkyuu Shirei - Solbrain (Japan).nes  

Using an IPS patcher such as Lunar IPS to patch the rom.
You can find the rom on archive.org.



     3) Known issues:

All of these are pretty minor cosmetic things. 

- During the intro, you may notice that random garbage sprites will overlay with the protagonist's face during split seconds.
This is actually a glitch with the original Solbrain, it's just more noticeable in my hack. 
I was unable to fix it as changing those sprites will also change the water splash art during stages.

- During the intro and outro, the protagonist is blue instead of green. They could look better, also.

- The timing of the colour flickering of the red vest is slightly different. I don't think anyone would have noticed though.

I may try and fix/improve these in a future version. The way palettes are handled in this game is kinda of a mess so for now this is
what it is.
