I've tried using my BIOS to underclock the CPU, but the temperatures were still high. I'll give this utility a try, though. Thanks. You will need to set/create the SATURN_ROOT environment variable to the root directory of the SDK, which is installed to your home directory under saturndev/saturn-sdk by default. This environment variable is not too difficult to add to the installer for Windows, but Linux requires some more work (I'm not sure why it's not built-in to the Qt Installer Framework for Linux). In Code::Blocks, you will need to go to Settings/Compiler, select GNU GCC Compiler for Hitachi SH-2 from the drop-down, navigate to the "Toolchain executables" tab, select "Auto-detect" next to the ellipsis where the "Compiler's installation directory" area is, then "Set as default" which is under the drop-down for "Selected compiler" if it detects the directory correctly. EDIT: After trying to run it under Windows, the linker script seems to be missing. I'm not sure how this happened. For now, you will need to download the linker script from https://raw.githubusercontent.com/SaturnSDK/Saturn-SDK-Sample-00-Basic/master/Source/Saturn.lnk. As it's pretty late over here I'll have to look into this later.
