SDRAM Test Core & Final Poll
🕑 Added 2021-01-08 17:27:15 +0000 UTCI know you are tired of SDRAM trials. So am I. So this will be the last one.
I have built a memory test, which uses the SDRAM logic I use on my cores (including CPS). There are two versions: 48 MHz, and 96 MHz. Both will show a green screen until a problem is detected. Then, the display will turn red and stay red.
Each time screen goes from dim to bright and back to dim; a test cycle has been completed. Only the first 32MiB of memory are tested.
Please unzip the attached files to the root of your memory card. The files are available in JTBIN too, but I have not included them in the update tool because you would get the MRA merged with your arcade files. And I guess you don't want that.
Today is the last day I devote myself to the SDRAM. Starting tomorrow, I am back to arcade core development with the explicit goal of a CPS2 beta in January.
(the attached file is for MiSTer, MiST and SiDi files can be found in JTBIN)

Both modes passed on a recently ordered 128mb module from MISTeraddons for 40+ minutes, as well as The Punisher attract mode for 40+ minutes, as well as all the gaming I've thrown at it.

96Mhz almost immediately fails, 48Mhz works fine on Antonio Villenas 128MB module over here
