LLTPHack with SA-1

[apfel]

I'm trying to run the latest LLTPHack (https://spannerisms.github.io/lttphack/) and only get a black screen but I can hear the sounds when pressing some buttons. Did someone mange to get this hack up running on his Mister FPGA?

This version should be used by any system that can properly emulate the SA-1 with 256kb of BWRAM

Tested my hacked rom with snes9x and in snes9x it's working.

same here. applied the romhack and getting a black screen

i do think this could be fixed with a header edit. but im not 100% on what header to add, or remove

It appears that the core is only built with 128 KB of cartridge SRAM. There are further dependencies on this address width in the SA1 code, and I have no idea whether the design would still fit if the size were increased:

Code: Select all

localparam  BSRAM_BITS = 17; // 1Mbits

edit: I managed to bodge out the SA1 dependencies, and it looks like 256 KB of cartridge SRAM will not fit as-is:

Code: Select all

Error (170048): Selected device has 553 RAM location(s) of type M10K block.  However, the current design needs more than 553 to successfully fit
