 		 #155783 - Memory Size
Responding to: ???'s previous message
You can not assume that code size is similar between to different CPUs. How mush flash did you actual use. Not all 128K. 64K is a very big program for the 8052, unless you have a lot of tables.
Note that if you are using a 40 pin AVR the pinout may be similar (or the same) Atmel makes 8052 Chips also.
8052 does not have as many free tools as others CPUs. it is older than free. Note that you are looking for a simulator , not an emulator. An emulator is hardware and not free. Not that the 8052 has a small stack if you are doing some kind of elaborate mini O/S. Plus it is not great for context switches. As for C, Keil is the best. but the Free version are limited to a few Kbytes. SDCC is free but is said to have a big learning curve. I do not know about simulators. Note that there are "debuggers" which are simple emulators that run your code on your real CPU. This may be better than a simulator.

Other possible options:
PIC16 and 18 are similar (worse?) But have free tools and a simulator. TI MPS430 is actually 16 bits but competes in the 8bit market. Zilog???
