Re: What have you learnt most from programming in assembly?

(There was even a pinout of a Zilog Z80 in the back! Remember when user-level computer books/manuals had actual pinouts in them? Imagine trying to do that now.) You need to look harder but they're out there somewhere. My 2015 laptop that I still use it to this day has half of its user manual dedica...

Re: Why do homebrew cartridge releases get discontinued?

Most of the sales comes from collectors, aka the people who get mad when a game they own gets a reprint. If there's perceived future "rare" value to be had people will buy it regardless of the actual game in the cart.

Pokun wrote:The bank statement was finally removed in a later Pceas fork, as it really isn't that useful and only gets in the way when you are assembling something that isn't the standard HuCard. Nesasm also has some forks, but I don't think any of them totally removed the bank limitation.
What fork is that?

Re: Why you might want to watch Bandersnatch

It was great and I was hooked! It should be a template for any similar game since it's so well designed. I also enjoyed the aspect of the checkpointed retries which encouraged experimentation, not to mention it was integrated in the story itself. Another plus is that while it lets you "rewind" to a ...

Re: What assembler do you use for NES development?

NESASM. No shame! :lol:

It helps that NESASM is basically PCEAS2 since I use that very often, too.

Re: Problem converting 256 KB MMC-1 to 512 KB MMC-1

I could be wrong but my guess would be the reason more than 8k was not used is maybe that it was not cost effective at the time? That's exactly the reason why I myself wouldn't do it if my plan is to create a game with authentic 80s to 90s hardware: If it wasn't cost-effective back then and was the...

Re: Simulating floating point

Use 8.8 fixed point instead: it's a lot easier to manage. 8.8 looks just like ordinary 16-bit math, except that you only use the upper byte when displaying the results. Fixed point is great, and usually clamping off the LSB for functions that work with regular 8-bit integers is ok for most cases, e...

Re: Micro Mages (on Kickstarter)

Everyone should look at this thread and the kickstarter to see how you can effectively design and market a NES game with good appeal. Money well deserved! The 'o' in there makes me think there's some mirror-universe Rainwario out there building cartridges. ;) He's a fan of Wizard of Wor, perhaps? W ...

Re: Arcade Game Designer

Those games look simple enough that I think it may work... that being said I'll leave a possible nnes version to more experienced coders. I'd love to play with it and try to port it to the TurboGrafx though

Re: NES zapper + LCD

Because it doesn't? This only works because his lightgun works entirely differently than the OEM Zapper. ????? So what? A cheap circuit like that is miles better than wiring a duct taped wiimote/zapper combo to a raspberry pi. Can you seriously not see how viable this is if a cheapo clone can simpl...

Re: NES zapper + LCD

This is big, why is this thread so low key? Imagine the homebrews... If this really works then lightgun games can finally get out of the "I own a heavy obsolete display" domain.

You guys are life savers, thank you so much :mrgreen: By the way, I also need to clip off the MSB of a signed number too for some unrelated stuff, a la what you would do with an unsigned number (just ignore the msb), and I came up with this: ;Gets lower 7 bits of signed 16 bit integer, conserves sig...
