GDMike Posted July 25, 2019 Share Posted July 25, 2019 I was wondering why a NEW set of ROMs for the console hasn't been adopted. Is it because they would have to be GPL code? Is it because of the "odd/even" way they have to be read? Or just plain not an option? Lol just a question. Quote Link to comment Share on other sites More sharing options...

(Also, I assume he meant the CPU ROMs... we have lots of ways to replace the GROMs ) Edited July 26, 2019 by Tursi 1 Quote Link to comment Share on other sites More sharing options...
+Lee Stewart Posted July 26, 2019 Share Posted July 26, 2019 It would break a lot of software, including fbForth, because they depend on routines like SCANKEY (calls KSCAN) residing at specific locations byte combinations in the current console ROM. Also, the ROM itself depends on convenient byte values scattered here and there that were used to save precious memory. ...lee 3 Quote Link to comment Share on other sites More sharing options...
