We only have the SMB1 ?-block (block-193) which turns into a "Overworld" used block (block-192), as well as the overworld brick block (block-188). The underground brick block however would turn into an overworld used block if it would hold a powerup or coin.
The official castle / ice bricks and special blocks are completly missing. But since this might not be enough I also modified the sets for usage for fire and lava areas (means the red blocks won`t hurt you, they would just glow red-ish because of the environment), for desert levels, night and underwater. That ought to do.
I took the official files (from SMBX of course) as base and compared them to rips to see if the used colours match exactly, so I hope 5438A38A can use these sprites witout any major modifications. So far the special blocks section of "Super Mario Bros." only contains 4 blocks, if everything listed above would be included it would rise to 21 blocks however (not counting the effect sprites).
