Hello,
so I coded up some PIC ASM code to do a quick EEPROM read, bit-toggle and EEPROM write, to switch between two 128K games. Both games utilize the RAM, this is where I started freaking out. I bought 100 MDIP 32K SRAM chips a few weeks ago, in anticipation of the new board. Every single one I have tested, creates some artifacting in Sirius. I thought my board is to blame, so I built a hokey MDIP to DIP adapter and used one of the 62256 DIP SRAM chips (which I also bought 100 of, for the MegaCart+ boards). Here is the result...
I wonder what the deal is with the MDIP chips, they are supposed to be the same speed.
