Re: Reservation of mapper numbers

Here's another kind of test case to discuss. There are a number of roms which cah4e3 has dumped which are implemented in fceumm/fceux sources only via UNIF. Due to some emulator codebases only supporting .nes file extensions, or maybe some other reasons, they are actually unif files renamed to .nes,...

Re: Reservation of mapper numbers

here's some other information about virtuanesEx, and a good test case to discuss. here's the scenario: some clowns dump a rom, and figure out how to emulate it. they upload the roms to Tszone-fc.ys168.com (KT-1019 and KT-1020 in the first folder) they also upload virtuanesEX to this site, in the las...

Re: Reservation of mapper numbers

I dont understand. Are you proposing to formally define those in the memo, or do they have some relationship to mapper28, like, they can be subsumed into mapper28? Or are we defining mapper28 in terms of those others depending on chr/prgsizes and register configuration, and so the definition of thos...

Re: Reservation of mapper numbers

Unlike GL extensions or RFCs, we are desiring to go in order and have the participating emulators skip as few memos as possible. I'm not sure anymore how much wisdom we can glean from that. Perhaps we can make a forum topic for a memo proposal, and do the discussion in there. This is similar to GL e...

Re: Multi-discrete mapper

I noticed that the nametable visualizer in NESICIDE reacts instantly when I press F8 to step to the next instruction. This is convenient; FCEUX's doesn't. Doesnt this conflict conceptually with the idea of tying the nametable viewer update to a specific scanline? There would need to be a way to cha...

The crash is fixed for 2.0.2 by upgrading to cah4e3's latest code.

There is graphical corruption in the title screen and intro cutscene due to issues with these mappers which havent yet been resolved.

You are right; i stand corrected. It would seem that the XD fceus have different mapper code than the other branches; which is different still than what FCEUX has (perhaps FCEU-mm made some architectural changes to the mapper system and that is what we're using, since FCEU-mm has tons of active deve...

this will be fixed for 2.0.2. Thanks for reporting this; however, I am more likely to fix bugs if you post them through official channels to ensure that I find out about them. Also, as far as I know, FCEU has always had this problem with its cnrom mapper. In general, FCEU codebase has many limits wh...

That is an interesting question. I am open to suggestions. What do you think is the best way to address banks? Are there any mappers that can switch in both 8k and 16k? If not, then I could pick based on the mapper. But would that be confusing? Do you think it would be better always to address banks...

Oh. Perhaps he meant to set the breakpoint in terms of the .nes file address. That's more or less what it is going to be, but it displays it in terms of 16k chunks.

I thought he meant to save the list of breakpoints into the nes file or something bizarre like that.

What if the debugger could dump and reload its list of breakpoints? Would that be satisfactory?

What if you could name each breakpoint, to remember what it is there for?

I think the fceux internals are a bit jumbled and mapped rom banks is all that is easily achievable!
