I found someone else encountering this glitch:

But I don't know what emulator was used to capture that video. This might be a real bug in the game.

Castlevania III Sunken City Glitch
In my emulator ( Nintaco ), rarely, but sometimes, when I kill the final boss in the Sunken City level of Castlevania III, I see the following glitch: https://imgur.com/a/DjI9ZKs I was wondering if this is a known bug, or if this is an emulation issue. I routinely beat the game and I never noticed a...

Re: Nintaco -- NES-Famicom-Dendy Emulator
I finally got around to updating Nintaco . A list of changes can be seen here . During 2019, I primarily worked on a complicated bot to play another NES game, an AI more advanced than CastlevaniaBot . Unfortunately, after completing about 90% of it, my work project and team got terminated. That trig...

What is the point of this type of spam? Is this some way to acquire user names or something?

Re: Ice Climber in my Emulator wants to write to CHR ROM?
Hello, So I have been making some progress with my emulator and managed to have visual output with my PPU. Donkey kong main screen renders fine. Tests are also able to print to the screen fine. So another game I tried to render the main screen of was Ice Climber. The text renders fine, but the big ...

Re: Tetris disassembly, Mod framework, Lua unit testing
This version is probably not as useful for the AI play since it only lets you select 5 different heights (like in Type B), but it is nice for normal gameplay. If you wanted it to be able to choose any height, you could use an approach like I did in my playerid hack (which is part of taus for techni...

Re: Tetris disassembly, Mod framework, Lua unit testing
I tracked things down more. The reason your change broke the timing is because spawning the next tetrimino ($988E) waits until copyPlayfieldRowToVRAM ($9725) has copied all playfield rows (based on vramRow). Since only 4 rows are copied per frame, decreasing the total number of rows will decrease t...

Re: 8bitworkshop - online IDE now supports NES
That looks really impressive. Is it really possible to develop a game in C? What about the function call stack frame performance hits, etc.? How do you break a C program up into swappable banks? I guess I'm really asking, is this a toy or can you really do something with this?

Re: Tetris disassembly, Mod framework, Lua unit testing
I made a hacky hack Thanks for the IPS. I made a very similar hacked version and I even used the same curtain tile to fill in the lower space. But, as mentioned, my changes broke the timing. There is a loop that copies the playfield to VRAM. I alterated that loop to only copy of the upper region, w...

Re: [Help] My guess the number game one-liners in Family BAS
Why only 1 line? I'm challenging myself to make those two guess the number one-liners in as little code in Family BASIC as possible. I was kind of hoping that someone was running a Family BASIC contest or code golf. 1-line challenges in a multitude of languages have been around for ages. And the pr...
