- DMA transfer timing or FMVs lock up
- Commands spanning multiple blocks
***
### Hot Wheels Turbo Racing
- DMA timing or hangs on startup/ingame
***
### Syphon Filter (series)
- Infinite DMA linked list/chains
***
### Valkyrie Profile
- Requires DMA timing otherwise battles time out/lock up
***
### Red Asphalt
### Dukes of Hazzard, The - Racing for Home
### Little Princess - Marl Oukoku no Ningyou-hime 2
- Hangs in various locations if DMA timing is off
- Locks up if DMA timing is off/CPU does not run
***
### Suikoden (version 1.0, not 1.1)
- Two releases, the old version corrupts palettes if you don't emulate fetch timing from the BIOS ROM
- It executes a bunch of memmoves (running from uncached ROM), which can't complete too quickly, racing the DMA
- Interestingly, version 1.1 spams printf during the same screen transition with a bunch of a's and a number suffix
***
### Deadheat Road
- Kicks off a DMA chain involving a VRAM fill, which takes a while to complete,
- then does a memcpy out of uncached ROM
- then zeroes out some of the headers in the DMA chain before it finishes
- Will hang emulators (if they don't properly handle infinite LLs) or the game will time out and skip a bunch of texture uploads in the loading scren
***
### Alice in Cyberland
- HUD/UI will flicker during battles if draw and DMA timing is instant
***
### Battle Arena Toshinden
- Runs too fast if CPU/GPU timing is off
***
### Bust A Groove Series
- Audio will drift slowly over time with game if GPU frame rate is incorrect
***
### Championship Motocross 2001 featuring Ricky Carmichael
- Sensitive to DMA timing - rider will be missing from bike if incorrect
***
### Evil Dead - Hail to the King (USA)
- Needs timer0 clocked from dot clock emulated
***
### NASCAR 2001
- Main menu music will drop in and out if SPU interrupts are not re-triggered after enabling
***
### Skullmonkeys
- Requires GPU coordinate truncation/sign-extension otherwise objects will be missing
***
### Formula One 99
- Requires CPU icache emulation
***
### Spyro 2 PAL
### Spyro 3 PAL
- Libcrypt protection is really nasty - the cop0 instructions to grab are xor-obfuscated, and written immediately before execution
- Naive icache implementations will break - you need to handle partial line fetches from non-16-byte-aligned addresses
***
### Parasite Eve 2
### Disney's Treasure Planet
- Sensitive to MDEC timing
***
### Pro Pinball Series, True Pinball
- Requires interlaced rendering (line skipping) otherwise hangs on startup
***
### Dead or Alive
### Mr Driller G
- Requires interlaced rendering, otherwise artifacts on screen in various locations
Vamp### ire Hunter D
***
### Vampire Hunter D
- Screws with GPU packets after enabling DMA, requires CPU to run in parallel otherwise menu will be black
***
### Jackie Chan Stuntmaster
- Triggers interrupts by setting cop0 bits in software, can be tricky for recompilers
***
### Remote Control Dandy
- Requires VRAM transfers to be masked to 9 bits
***
### Shadow Master
### Threads of Fate
- Branches in branch delay slots, fun times for recompilers
***
### Tales of Phantasia
- Battle transitions will finish too quickly if GPU draw timings are not emulated
