My GCC 4.7 port hasn't received enough widespread testing yet to see what bugs I've introduced ... but Alex Marshall's "liberis" examples all work properly, and another user has ported a simple shoot-em-up to the PC-FX with no apparent problems.

. . .

If someone is interested in being the "goto guy" for a VirtualBoy version of my patches, then I'd love to hear it.


I'd be happy to help with that and put a build together for testing. There are a few reasonably large Virtual Boy projects around which should give your patches a good workout. :)

Hi Elmer

Welcome, and great work.

Does anyone actually write interrupt-handlers in C???


Yes, using the interrupt_handler function attribute.

Quote:
The compiler generates some pretty slow register-saving code for them, so I sort-of assume that folks just write then in assembly. Am I wrong?


From what I remember, when a function is declared with the interrupt_handler attribute the compiler generates save_interrupt and restore_interrupt prolog/epilogs, which save/restore only four or five registers. What have you observed?

> Am I correct in that I can use an EU Mega Drive 1 power supply?

Hi. A PAL Megadrive adapter is what you should be using, i.e. a 9V DC center negative adapter. Using an AC adapter may damage your Virtual Boy.

Personalities clash sometimes. But we're all hobbyists here, we're all presumably doing this for fun. We've all agreed that extending the competition deadline is a good idea. Let's make the most of it.

'tis the season of goodwill, after all. (-:

Looks great, Mr. Anon. No shadows, though?

The graphics are converted from the arcade game. The Virtual Boy and PC Engine have comparable sound hardware.

That's right, you didn't. In almost 1400 words there's no mention of the 15 Feb 2010 email, and nothing about jojobean's attempt to scam the owner of Faceball with faked Zero Racers source code. Everything DogP, Krisse, myself, and others, have brought to light regarding jojobean's fraudulent activities you've apparently dismissed as untrue, whereas jojobean's extremely dubious assertion that he was simply trying to raise money to acquire Faceball and Dragon Hopper is taken at face value. Whether you think we're all deluded or lying or simply mistaken I don't know, but your suggestion that by doing what we did we somehow "screwed up much greater things for the rest of us" is totally unfounded.

I'm afraid the cold hard truth is that jojobean lied about the Bound High ROM he was selling being a fully working cart dump, and he lied about knowing someone who owned the cart. And if he lied about that, and he did, and more besides, there's absolutely no reason to believe he wasn't also lying about Dragon Hopper as well. So this:

I assume you're refering to Krisse's version of events. I think you need to make that clear to avoid any further confusion.
