I recently added my company's (Rampage Robotics) base robot board designs to my svn repo. http://svn.rampagerobotics.com/<br />I would like to help develop.<br />Maybe we can figure out an fpga cart for gameboy.Jose Torreshttps://www.blogger.com/profile/03888277865450154187noreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-867004408236418952009-06-20T21:44:45.503-04:002009-06-20T21:44:45.503-04:00That's what I had in mind too, but I wasn'...That's what I had in mind too, but I wasn't sure if I should bother with that approach or not because I'm not sure if the SNES can supply enough power to the PCB to run the FPGA and other circuitry. Do you know how much current the SNES is capable of supplying to the PCB? I think I read somewhere that even super FX carts came close to the limit.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-81118550550920113662009-06-20T15:28:49.173-04:002009-06-20T15:28:49.173-04:00right now, i'm just doing it the boring way. i...right now, i'm just doing it the boring way. i power the fpga board externally and boot it before the snes. I think i've worked out a better way to do this by basically hardcoding a jump instruction behind a buffer that I can disable once the fpga comes up, but I haven't bothered trying it yet.scottjghttps://www.blogger.com/profile/00865187083873717495noreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-84090211065430629602009-06-19T10:53:45.262-04:002009-06-19T10:53:45.262-04:00How do you get past the problem where the FPGA has...How do you get past the problem where the FPGA has to come up before the SNES? Do you give power to the FPGA board so that the FPGA can configure, then do you power the SNES up after configuration? Or, is there enough time for configuration while the SNES interfaces with the CIC chip?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-705536812493836035.post-36690443145170889882009-05-11T00:39:00.000-04:002009-05-11T00:39:00.000-04:00Wow, thats excellent!
