Swinging swords like Shinobi

Thursday, October 2nd, 2008

As I’ve expected previously,this game simply uses different addresses for the video ram and two planes instead of four.It appears to be an earliest revision than the other games of this hardware,namely:

urashima -> daireika/mjzoomin -> kakumei/kakumei2 -> suchipi

Needless to say,the game now “somewhat” works.Still to do: fix/find the tile banking (as you can see in snap 4) and double check the scrolling registers.

Can it be all so simple then…?

Got a look into the jalmah.c driver again,fixed a regression which caused an hang bug into daireika,mjzoomin and urashima and fixed a protection issue with the random number generator into Mahjong Daireikai.Game now fully playable with some annoying video issues here and there.
