The BCM2385 on the Raspberry Pi model 1 has 45 GPIO pins (you'll need 32 to interface with the Gameboy cartridge bus) that are (apparently) designed to operate at 125MHz (although the partial datasheet cautions that they may not run that fast when driving high capacitance outputs. In principle, there's certainly no reason it isn't possible. As Gameboy games take ~64-1000 KB space, even the RPi Model 1B with 512 MB memory could hold a large number of games.
RASPBERRY PI GAMEBOY ADVANCE EMULATOR SOFTWARE
The motivation for doing such a thing, apart from the fun of trying, is that you could store multiple game roms, and perhaps design some Gameboy software that lets you choose a selection. My understanding of how that matches up with bus speeds etc. Assuming no OS overhead on the RPi, is there any reason why such a setup wouldn't work using an RPi instead? Naively my thinking is that even the RPi Model 1 B is clocked at 700 MHz (with the 3B at 1.2GHz), whereas the STM32F4 is 168 MHz, so just based on CPU cycle speed there shouldn't be an issue. There is an excellent set of blog posts here: in which someone has done exactly this idea but using the STM32F4 MCU rather than an RPi. There could also be some Gameboy software that is initially loaded to the Gameboy which allows you to select from a choice of stored game roms. I'm assuming no OS is needed on the RPi, just some interfacing software which maps the memory addresses properly. Unlike that previous question, I would like to know if there are any specific hardware limitations to trying this for a Gameboy (not NES) using a RPi (not a generic MCU). It would also need MBC functionality to be able to emulate generic games.

By this I mean mapping part of the RPi's SDRAM to hold game ROM and RAM, interfacing to the Gameboy's 32 cart pins via the GPIO header, so that the Gameboy believes a normal cartridge is connected.

RASPBERRY PI GAMEBOY ADVANCE EMULATOR CODE
The source code and technical details for the project can be found on Sanderson's GitHub repository under the GNU General Public License 2.0 he warns, however, that it is to be considered "in a 'works-on-my-machines' state, so expect build issues.This is an extension to the question NES cartridge rom emulation with arduino or pi?, which asked whether it would be possible to physically emulate a NES cartridge using an Arduino/Raspberry Pi (RPi). Sanderson has plans to improve the emulator too: For the Raspberry Pi Pico, and other RP2040-based microcontroller boards, he hopes to add support for connecting a USB keyboard rather than having to pass keyboard traffic via the UART, the ability to drive an original BBC Micro-compatible CRT monitor, connect a second Raspberry Pi Pico as a Tube or SPI device, interface the emulator with the Pico's general-purpose input/output (GPIO) pins, support loading from tape, and more.

Emulation, though, can be power-hungry, and Sanderson has taken full advantage of the two cores to keep things ticking over: The emulator runs on one core, while video display work is handled by the second. With two Arm Cortex-M0+ cores running at up to 133MHz stock and higher when clocked outside of spec plus 264kB of memory, the Raspberry Pi Pico is considerably more powerful than Acorn's classic BBC Micro or even upgraded BBC Master 128.
