There is a guy, knowing from the TI-99/4A Computers Forum on AtariAge, who makes a TI-99/4A with a Pipistrello FPGA board where an existing oldschool TMS99105 processor is used to implement the rest of the TI within a FPGA. (Just the opposite of the FPGA Module project.)

- And his repositories on GitHub
Another guy (also knowing from the AtariAge Forum) who developed a TMS9918 compatible VDP (called F18A) with an FPGA. His places with information:
