For FPGA, particularly 8 bit projects, I recommend you take a look at the Lattice ICE40 series, particularly the ICE40 UP5K.
This chip has (as well as dual ported block ram) 128kbytes of on-chip static RAM. There is also a very inexpensive board for prototyping, the upduino 3.1 - https://tinyvision.ai/products/fpga-dev ... MF7PAMSaBL (there is a European distributor). Also there is a full open source toolchain for the chip should you not want to deal with a bloated IDE. The upduino board also needs nothing more than a USB lead since the programmer is built in.
I currently have an "econet SoC" running on a up5k, still under development (I was working on the PCB today), much prefer it to the Xilinx stuff, especially now that Xilinx have seemed to abandon all their smaller FPGAs (not supported by their current IDEs, and the Webpack IDE being unmaintained at this point for years).
