NESpire general discussion thread

[DJ Omnimaga]

One thing to keep in mind, though, is that this NES emulator may not necessarly be in C. Maybe it is, but if it is in assembly, then it doesn't mean C would be able to achieve this. Just noticing the framerate at which the raycaster runs I am not so confident C would be able to pull a fast enough SNES emulator, for example.

[Goplat]

Goplat, if you see this, could you tell us how many times faster the emulator will run if you get rid of speed throttling? I wonder if it's the same speed as a GBC?

Currently, it can run at a bit under 2x the speed of a NES, in nspire_emu. On a real calc this would be somewhat slower, since nspire_emu naively assumes every instruction takes one cycle. Also, implementing sprites more accurately might slow things down as well. Still, should be able to go full speed even without frameskipping. I'm not sure what you mean by "same speed as a GBC", since the GBC can't run NES games.

If anyone wants to try out the current work in progress: here it is. (Don't expect many games to work at this point.) There's no UI yet, so you have to concatenate the emulator to the ROM ("copy /B nes.bin+somerom.nes nes.tns" in the Windows command prompt). Game controls are like gbc4nspire (Esc = A, Tab = B, Caps = Start, Clear = Select). Also P = pause, Q = quit.

Speaking of GBC, while we are making emulators...

[DJ Omnimaga]

Oh I meant I was wondering if the emu was able to produce speed as fast as the gbc4nspire emulator (I know it only does gb/gbc, not NES) when speed throttling was turned off. It was just an example. I'm glad to hear the emulator can run at quite fast speed

Sir: Do you mean you want a GBC emulator for the Nspire? Because you can simply use Calc84maniac's emu for that

[ztrumpet]

Wait a minute!  We have a calc on the DS, but no DS on a calc.  Some of the Nspires do have a Touch Screen now.

[DJ Omnimaga]

No, no Nspire have a Touchscreen. They have either a clickpad or a touchpad.

[ztrumpet]

Whoops, sorry.  Touchpad.     My bad.

* ZTrumpet feeds himself to the lobster...

[Deep Toaster]

Yeah, touchpad, unfortunately Maybe we could play with a blind lower screen? They're not used that much in many games.

[qazz42]

err, do I need 1.7 ndless or 1.1? or 1.0

[apcalc]

It worked on OS 1.7 for me, so I would assume 1.7.

[qazz42]

meh, fair enough

[Goplat]

err, do I need 1.7 ndless or 1.1? or 1.0

Either one should work.

[qazz42]

oh, ok, I will use 1.7



CASTLEVANIA DIDNT WORK!!?!

can you upload the one you made (oh ,wait, that would be ROM sharing )

[Goplat]

It worked when I tried it... Can you verify that the combined file is exactly 142,028 bytes? And how did it not work - did it just exit immediately, or reset, or hang? (if it hung, could you still exit with Q?)

[DJ Omnimaga]

Maybe it was a bad ROM too?

I can't wait to see more development on this.

* DJ Omnimaga wonders if after a NES emu we will finally see the following then runs away (note, the screenshot below is fake, before people get ideas...)
