Thanks to your support I visited a sellert today and bought new games to translate to FPGA. I am really excited about these titles. All the PCB's worked but Rastan Saga had no sprites on screen and Nemesis (Gradius) seems to be completely broken. I may repair them as part of the conversion process.
I do have a backlog of tasks but I didn't want to let pass the opportunity of visiting this seller and I think it was worth it. Please let me know what is your favourite from the games I bought today. Oh, you can have a look at the PCB photos attached to this post.

Gracias al apoyo recibido por vosotros hoy he visitado a un vendedor de placas y he comprado varias para pasar a FPGA. Son títulos míticos para mí y todas funcionan. Bueno, el Rastan Saga no tiene sprites y el Nemesis está roto del todo. Pero seguramente podré arreglarlas mientras las convierto a FPGA.
Tengo muchas cosas pendientes aun pero no quería dejar pasar la oportunidad de comprarlas. ¿Cuál es vuestro juego favorito de los que he comprado? Por cierto, las fotos de las placas están adjuntas a esta entrada.

Rastan!!! Hope it comes one day!

MAME source code has a lot of information, although it usually misses bus timing aspects so you need the real board or the schematics to fill the gaps. Of course, games with full schematics available and no custom chips are the easiest to do and you can also be confident about the fidelity of the conversion.

Hahaha. ;) but I quickly realized that It was not an easy pick for a start, with all those Konami proprietary ASIC. Then I was more working on the audio part of the board, because only one IC is unknown (5289) and it seems to be a simple table. But without the real hardware at hand it is not that simple. I checked the code in MAME but there is no table data for it. It would be easier with the real hardware to increment the 12bit address bus and send the control respectively on LD1 and TG1 to see the result on the 5bits output on each channels to recreate the table
