the problem is that your laser bar will be more than 2 meters long when you consider that one laser is 0,8-1,0 cm thick.
i had this idea too but this is very unpractical and the gaps between the laserdots are too big.
an other possibility is a LED wall…
it looks like i found a solution for that problem.
i used a hotglue pistol to fix it.
I used only a little bit of hot glue and after that i used gaffa tape over it. the flicker was gone an not came back so far.
Tower of Infinity, much about your post is very strange…
you ask for roms etc but you gave us no proof for what you want to do.
You said that you have a 47% version of Dragon hopper.
You can Proof that with Screenshoots…
BTW: why should have IS only a 47% version when the game was almost done???
about dragon hopper.
since this game was from nintendo/IS, the source IS NOT lost.
Nintendo has a big archiv for such things.
I belive thy dont want to give the source out.
