Felipe Junger
@felipejunger
I build commercial C++ emulators and systems software.
BrazilWhat I'm looking for
I delivered RetroFreak's commercial Famicom/FDS emulation core in C++, supporting cycle-accurate CPU execution, synchronized graphics and audio, and disk emulation.
My systems work spans CPU and microcontroller emulation, reverse engineering, debugging, and performance tuning. I also built mRL78, a C++ emulator for Renesas RL78 microcontrollers.
I contribute to QEMU, where my ARM11 MPCore SCTLR reset-value fix was accepted and applied to target-arm.next after local bare-metal validation.
