Transistors are great for small amps but big amps require the use of multiple transistors. You'll find there's a lot of IC chips out there that are just amp chips which have the same effect as a transistor amp. I mean it's the same thing as either building your own clock circuit out of a 2 pin crystal or just buying a 4 pin crystal oscillator that contains the entire clock circuit inside a metal can.

Lately I've been focusing on the software side of things and have taught myself how to hex edit rom files. Finding the data in a rom file that you want to change is a major @#^@#^#@^@&$ but if you can manage to find it you can do some pretty cool changes.

That's good, sounds like you have a good science teacher there.

Yeah that is right, most big amps use IC op-amp chips (where op-amps themselves are made out of several transistors) or chips containing several transistors in special configurations making use of transistors as active loads i.e. cascode amplifiers. I still think transistors are very important to know some things about if you have an interest in electronics.

I've briefly edited hex edited files before, it would be interesting to learn more about.

I just used a lot of google searching and found some tutorials and tools to use to help me hex edit things like colours. Hex editing programming is more difficult to do though. I also learned a lot about how cps1 hardware stores the pallette data for games. Now I can see the hex values and figure out how to adjust the rgb values myself without using a tool it's really not that difficult once you learn it.

i did a lot of each, i got help from people on the forums, i google searched a ton, and my science teacher helped me a tad bit with the electrical side of everything

The "true rgb screen" failmod



from here:

http://shmups.system11.org/viewtopic.php?f=4&t=22334

why this fails:

His screen has nothing around it, no way to carry it. The whole thing looks retarded. And also properly encoded s-video or component video look just as good as rgb on a crt.
