Re: Emulation quesions

I would like to contribute in some way, but I'm still too busy studying English these days, and loads of things to do. I'm planning to take your source code by the end of November, and make a few additions to it. I wish I have the time btw. Contributions are very welcome. If there's an error with e...

Re: BASIC disassembly

Here's something from Wizzdom issue 3, page 4, which intrigued me. The description of the self modifying program is a little confusing Start of program area is 220,0 followed by 5 characters for line number then a space, then 4 characters for DATA: therefore the 0 is at the tenth position. The actua...

Re: Emulation quesions

Ok, how about we call a truce. I agree not to interfere with how you run here, you agree not to interfere in what I do? Sound fair? The only things I ask you is to apply the same rules to everyone, regardless of how long they have been here. Sound fair too? Also, I hope you can smile and maybe laugh...

Re: Emulation quesions

Let's put the shoe on the other foot for one moment. Had I joined the community, and my first public communication with you was "hey - your website is not cool, and the name is wrong'. Quite rightly, you would smile and wave at me, and then proceed to ignore me. Why? it's extremely rude and disrespe...

Re: BASIC disassembly

I have had a closer look at the BASIC cartridge (VTech 1983 release), in hope to find some JSR ($xxxx) or similar entry, possibly finding a way to extend BASIC with a machine code routine of your own. Unfortunately I haven't found any such entry. Base address + 0x0743 : PEEK It's actually 0xA745 fo...

Re: BASIC disassembly

Which address is 7000? The charset in BIOS (note: not the Basic cartridge!) starts at $F880 according to my notes. For that matter, I never disassembled the Basic cartridge looking for a charset, as my homebrew would not depend on the Basic cartridge anyway. I suggest you look at how a 12k ROM load...

Re: BASIC disassembly

Yes, we found the BIOS character set but it doesn't quite contain all the symbols as used by BASIC so the BASIC cartridge must contain at least some additional symbols not found in the BIOS, or perhaps a full 512 byte (wow!) character set that is copied in its entirety like I started with on the Re...

Re: Emulation quesions

Hey everyone, Just wanted to say thanks for taking the time to download the emulator from sourceforge. Although not earth shattering, 14 downloads from a community of 32 people is appreciated. Over time I hope to get all the documentation I have together and put that up there too - so the next guy d...

Re: Emulation quesions

Ok, latest update. Marat has just informed me of a potential rollover bug in the total cycles counter - I've fixed it locally, and will push it up tomorrow.
