> Does this mean that Star Wars Arcade will be fully emulated in a close future?
it means there is a very good chance of being able to extract the Coprocessor code from the chip, which will make Star Wars emulation possible.
It doesn't mean it will happen 'soon', and it doesn't *guarantee* success, the decapping process takes a while and requires a suitable time slot to do, the data entry and verification takes a long time, and OG has already had to rewrite the CPU core for Virtua Racing to run it's real CoPro code, so there could still be bugs to iron out even once the program is acquired.
For all we know this part could have EPROM instead of Mask rom, and while that is very unlikely, again can't 100% rule it out. If that turns out to be the case new techniques will have to be considered.
It is however an absolutely essential step if we want to see Star Wars, Wing War and NetMerc properly emulated. The correct co-processor functionality is essential to those games behaving as they should.
Emulation is science, this is part of the discovery process.
