 Lynx Cart Bug Patch [message #1570] |

I've been working on putting together Lynx dev tutorials and I was testing out Karri's Lynx demo cart building process with the cc65 toolchain. The cart that was produced crashed Mednafen 0.8.C because it was assuming the game data was exactly the size of the memory bank. On my debian Lenny box, memcpy segfaults when trying to copy beyond a memory buffer end. I fixed the bug by first calculating the min(gamesize, mBankMask0+1) and then used that for the memcpy. The patched version works and runs Karri's demo cart correctly. I wasn't sure where to send the patch file so I'm attaching it to this post. edit: Apply the patch by uncompressing it somewhere, cd'ing into your mednafen root dir and then running the following: patch -p1 -i <path to the patch> It should only modify src/lynx/cart.cpp. Rebuild and then try out Karri's demo cart from the cc65 toolchain (also attached). --Wookie
