Re: Has anyone tried to obtain an "Official Seal" from Nintendo for their game?

Nintendo had an even tighter grasp on the supply chain in Japan during the NES and SNES eras. Nintendo franchised game stores received at least 10 times as much stock as independent stores in exchange for letting Nintendo dictate pricing, game placement, signage, etc.

Re: Questions about NMI, VBlank, DMA, & HDMA

1. If you have the vbank interrupt enabled (bit 7 of $4210 set), the processor jumps to wherever in bank 0 you have the NMI vector set to. "wai" isn't necessary for this, it just makes the processor stop execution until it gets an interrupt. If your game loop takes too long it'll also get interrupte...

Re: 65816 C compilers

It would probably be better to change the thread from "65816 C compilers" since the discussion's gone elsewhere. Anyway, my hot take is that I don't really see a target developer audience for this. If you're willing to put up with an antiquated 33 year old processor, you probably have an existing pl...

Re: Need some tips for a demo

Added complication is that the 2x2 is stored as 4 separate screens and not 1 large screens this means you have to do some "fancy" maths to work out the address. Base = (X & 40) << 8 + X & 3F This means you also need to be careful with your horizontal DMA if it crosses the "32x32" barrier. That's wh...

Re: SD2SNES PRO flashcart

Unless you want to use save states instead of practicing the game you're playing, this doesn't seem like a good upgrade (I think Ikari even mentioned that it was mainly done because the FPGA in the original model got EoL'd). That being said, if you don't already have an SD2SNES and don't care about ...

Re: Need some tips for a demo

What I did may not be the best way or the most efficient way, but it's pretty simple. I have a pointer in zero page called "scrollScreenAddr" that gets initialized to the first "screen" (32x14 tile tilemap)'s location in ROM. I also keep track of the leftmost column onscreen (this is essentially the...

Re: When have you used a language (C, etc.) instead of asm?

What I do is (if the logic is complex enough that writing it in straight assembly would be error-prone) write whatever piece of code I'm adding in a C-like pseudocode and then translate it to assembly once I have the logic down. If the resulting code is hard to understand, I comment it with the corr...

Re: Toshiba TLCS900/H instruction timings?

The H1 isn't the same as the "original" 900H, I think it says in the manual that it's a newer 32-bit variant. Anyway, I guess I'm pretty good at data hoarding, as the site I downloaded this stuff off of is down now. The info you want is probably in the file named "e_900h_chap3_cpu_6.pdf", but you wa...

Re: Who do you consider to be the snesdev/scene gurus?

Both the how to code tutorial and accompanying example code are on Textfiles (what I was referring to as "Pan's edgelord text demo" for reasons that become evident if you look at the code).

There's a bit of discussion about scene/industry overlap (both confirmed and speculated) in this thread .

Re: Aren't you afraid that NES Maker would just bring lazy n

Hot take: If you're afraid of your game being overshadowed by a "no coding required generic NES engine" game, maybe you should try harder.

Re: New tv set may not support rf?

In the US, a number of modern televisions have just dropped the type F connector altogether, instead being some combination of monitor and treacherous WiFi client. Haven't heard about that, digital OTA TV uses the same antennas as analog so it's surprising to see (every TV I've seen with a digital ...

Re: Why no SNES homebrew scene?

Based on this post by tomaitheous, I was under the impression it had all three of 5.37, 7.16, and 10.74 MHz modes. But consider the context to which I was replying: No problem, the 10.76 mhz is often forgoten :wink: Then I'll qualify: Every 16-bit game that is side-view and not flip-screen has to h...
