You develop Sega Saturn games in bare-metal C++ by compiling a custom SH2 cross-compiler toolchain and writing custom startup code with linker scripts. This approach bypasses external SDKs like SGL or libyaul, using direct hardware access APIs for maximum control and performance.

You access VDP1 and VDP2 directly in C++ using provided C++ abstractions and inline SH2 assembly. This enables direct interaction with hardware components like SCU and SMPC for creating custom game engines and low-level graphics libraries.

The best way to handle 3D math on Sega Saturn is by utilizing optimized fixed-point math routines. This approach uses vector operations and matrix transformations for efficient rendering, avoiding the performance penalties associated with floating-point operations on the hardware.

Yes, you can build a custom game engine for the Sega Saturn using this bare-metal approach. The Skill provides C++ abstractions for VDP1, VDP2, SCU, and SMPC, along with optimized math routines, enabling the creation of custom 2D or 3D game engines and homebrew applications.

To compile a Sega Saturn ISO image with custom startup code, you use the provided custom SH2 cross-compiler toolchain alongside your own `crt0.s` file and linker scripts. This setup facilitates building ISO images with precise control over memory management.

Bypassing SGL or libyaul for Sega Saturn homebrew development grants full bare-metal control for maximum performance. Writing custom startup code and interacting directly with hardware components like VDP1 and VDP2 provides deep insights into the console's architecture.
