Question

Hi everyone, first (proper) post.
I've picked up this Arkanoid 2, and I -think- that maybe the B08-04 ROM is missing.
Here's the display I see at title and game demo.
The game boots straight up; I don't think there's any sort of ROM check.
And here's my PCB
I downloaded the MAME ROM set and the B08-04 ROM chip is included there but my board doesn't have it.
The MAME ROM set didn't have the B06-XX ROM files that I labelled on my photo,
so I assume they are common to this board model or something and maybe included in some generic Taito board ROM.
I found this picture of the PCB online
http://www.arcade-museum.com/images/118/118124204862.jpg
and that shows the B08-04 chip in the top right corner.
Mine is an identical board but missing this.
I'm pretty sure I've been bullshitted by the guy I bought this from (he told me it was working fine), but I just wanted to ask
[edit: i'm now fairly sure it was an honest mistake and that he didn't know the ROM was missing, it may've fallen out somewhere]
1. Am I missing the ROM? Is it possible that there's a version of this board that doesn't have B08-04?
2. Do you think this missing ROM could account for ALL of the problems I'm seeing? Or is there likely more to it?
3. What kind of EPROM/EEPROM/whatever else should I buy to make this chip myself from the MAME ROM (is there a guide for this anywhere?)
4. Is 3 a good idea or will it be easier / cheaper to just buy it from somewhere (where?)
Many thanks in advance if someone is able to help :)
