I made it with partial success.
I edited the character table in your rom to run some programs in Portuguese and it worked well.
I added a customized mega assembler rom (I'm addicted to it), It worked, however it breakup megasd disk operation.
It appears that ocm--bios.dat with less than 512kb works fine.
I assume that working dead keys in keyboard depends firmware modification and it can be really difficult, no ?

Thanks.
MSX BIOS will map column / row to specific characters and might have specific behavior for things like á à etc
FPGA code generates column / row based on PS/2 keys
So, if you want certain keys to have different behaviors, you need to figure out which are the column/row they activate on your Portuguese BIOS, which PS2 key you want to use for those column/row activations, and work on the keymap vhd file for the keyboard layout you want to implement those changes (i.e.: https://github.com/gnogni/ocm-pld-dev/blob/master/esemsx3/sr... )
